The ABC 1 & 2 Shaftsbury Avenue is now known as the Odeon Covent Garden which has been split up into four screens, and still capable of showing 70mm on one decent size screen.

I did a one day relief some 40 years ago at the Ritzy Brixton, then known as the Pullman later the Classic, running a diet of split week Western pictures! As Stephen said, the projection room was a decent size. The projectors then were BTH Mark 2 Supa’s which could put on a good show I thought.

The old Odeon Guildford near me added a forth screen with its own projection room in the disused front stalls space. Now demolished, Odeon now have an 8 screen multiplex in another part of the town.

Here is the old Classic / ABC Hampstead opened in 1912 (demolished 2002) with the circle extended for screen 1, with two decent size screens in the whole of the stalls area.

I would hope that NOBODY in this day and age would consider 'twinning' any existing large theaters. I personally will not watch a movie in any 'plexed' theater, nor will I work at one. With increased competition from home video and the recent decline in business altogether, BIG theaters are what's going to give people a reason to still go out. If a customer can only see the movie in half of the theater, shouldn't they only have to pay half the usual price? [Smile]

Twinned theaters are an EXTREMELY depressing sight since they remind you of what used to be there. Here we have 2 big Century domes that once had huge screens and 1000 seats, both were split down the middle more than 25 years ago and now look just awful. I don't know how the people who did this can sleep at night.

Many split theatres have issues with decoration (especially earlier/cheap conversions)

Scale issues occur when decorative features are cut midway through their length. (Example Contrasts of style between the added and non added parts can also have issues (ceiling tiles often look out of place in older rooms).

The best conversions are when the decorative style has been reproduced sympathetically in the new auditoria. (although smaller screens are better kept more simple). I have seen a conversion (in a now sadly closed) cinema where the proscenium arch was copied and built in the main (former balcony) screen ( Both proscenium arches can be seen in this photo)

Please try to avoid getting round the decoration issues by emulating a modern multiplex and making everything dull.

Hi Steven

I agree on York, although this was hardly a conversion. We used the main printing works for screen 1, and built screen 2 in an existing ancilliary building at right angles to this. Each were good cimenas with 9m and 6m pictures. Screen 3 was built in a over the new foyer block with again a 9m picture and only 150 seats.

We prefer to chop cinemas up lengthways (OK, we prefer not to chop them up but we understand our clients' commercial pressures) and have had great success spliting the Curzons in this way. At Soho, we retained the original front half of the theatre and build a new projection room half way down the old theatre. This retained the original prosc, enabled a larger screen and made a good 260 seater with a 9m pix. Screens 2 and 3 are in the rear of the theatre, split down the middle, and each seat 120 with 5m pictures (all exceed SMPTE spec and are THX certified).

 -

The Mayfair (pix attached) was interesting - this was heritage listed and we had to retain the character of the old theatre. We dropped a wall 10 rows from the rear of the theatre and made a wide, studio style 80 seater. We'd wanted to split the smaller screen widthwise however means of escape prevented this - it's still a good theatre however.

 -

We think that theatres can be split successfully as long as (primarily) viewing angles are as good or better than the original theatre. Often theatres build pre 1960 didnt have screens that large anyway, but to do an effective conversion properly more strucural work (and cost) is needed and theatre owners can be hard to convince. In the case of Curzon this worked, and the Soho's audiences have increased 10fold since conversion (and the adding of bars, D cinema, conference facilities etc).

Century 21 in SLC were the same -the twin domes. Two big beautiful domed theatres with stadium seating at the time (and this was in the mid 70's with that monsterous flat screen for scope features..and projection were the V8 35/70mm in one side and a V8r on the other with 13k reel assemblies). In the later 70's, one dome was split in two to make an awful looking twin with very small screens and a horrible ratio for scope (like 2.1/1). Finally the one big dome was split in three and that ruined everything. Then Century got smart, tore all of this down and dropped a 16 screener in its place. Yet, the original twin dome concept was the best looking and presentable twin that could have been.

Yes, that was the point I was trying to make; it's much easier if you can gut the original building and start from an empty shell; probably easier still if you can start from scratch with a completely new building. Of course, that's not an option if you're faced with a listed building.

Creating good new auditoria within an existing old one is not easy, or cheap.

Find a good architect, with experience of this type of work, and be prepared to pay plenty of money.

Another problem, which I've seen in a number of places, is that the quality of construction of some of the big '30s cinemas was not very good, poor quality concrete, roof problems, water seepage etc. They became very expensive to maintain.

I love old theaters, I think it's a crime to humanity to destroy and old theater. I would say if it is some great art work and great architecture inside don't split it: renovate it

Twinned theaters usually suck. Bowling alleys is a pretty good description.

Proportion is the word we should use. I once found a "twin" that was very poor. We shortened it; then added on the the unused portion to make 4 properly proportioned theatres. The original 2 are no longer "bowling alleys" and the additional 2 are also properly proportioned. Louis

Minneapolis used to have its share of twins, triplexes, and the lot. The Har-Mar, Highland and Grandview were all somewhat ugly transformations & technical suicides of otherwise well built theaters (That is, if you don't count all the decor alterations Mann Theatres of MN put their houses through). The grand old Terrace, Apache & Cooper theaters were the unlucky ones... and quite possibly the underserving ones as trends sit now. The current fad is to build the biggest screen with the most amazing digital sound system around town, these days... A Cinerama house would have good luck pulling in a crowd around here.

But Minneapolis/St. Paul was developed by land-hungry deviants with little regard for movie houses, so the sprawl throughout the decade brought patrons to the exurbs, and away from the first generation burbs that these old palaces once occuppied.

At least the Riverview, Uptown & Heights were spared. Personally, I'd go for a twined, ex-balcony theater, if they proportioned everything right and left some of the original charm. But who in this area has multiple devotions like that?

Peter Hall's diagram shows an approach which seems pretty much the best possible for that theatre.

As Stephen Furley said, it all depends on the design of the theatre. At 1200 seats, I wonder if taking a chunk out of the back of the auditorium will leave only neck-crick seats for the auditorium remaining in front.

Along the lines of Peter Hall's design, splits of some (very large) theatres with balconies are typically to close off at the line of the balcony rail & then split. Some of these are horrible, some are just not too good, some are just workable. The benchmark for horrible is probably what they did to the Loew's Victoria in NYC which underwent the most ungodly mutant cell division with something like 3 on the floor in front of the balcony rail, thirds all facing front, the sides still having angled seating toward the center of the screen in the center auditorium, plus splits in the balcony & under. Horrible, horrible rooms. I think they maxed out at one point with 8 horrible, horrible rooms: 3 on the floor in front of the balcony, 3 under the balcony, 2 in the balcony.

If it's a theater with a big balcony, I've seen:
1. Wall dropped from the balcony rail to the floor, enclosing under the balcony, then that underbalcony area split back to front into 2 auditoriums (because otherwise it's really too wide & short) to form a triple. Projection booths are built on the floor under the balcony for the 2 new rooms, the old booth still hits the original screen which becomes the "big house" & still has a balcony. Unfortunately, entrance to the seats on the floor in the "big house" becomes via long corridors beside the 2 new rooms, & the theater becomes like a maze with some question as to whether it really meets life safety codes. The one in Peter's diagram doesn't have this problem, since it's one auditorium (instead of 2), centered, yeilding acceptable vomitories for the seats on the floor in the "big house". One auditorium centered under a big balcony is obviously better than two. Obviously, it also requires some remodeling of the side areas which become the vomitories for the front room.

2. A wall at the balcony rail up to the ceiling, closing in the balcony, then the balcony is split back-to-front (for the same reasons above) to form a triple. This gives you all the original seats on the floor & original screen as the "big house", easy entry to that auditorium through the original entries, easy entry into the 2 balcony rooms through the usual balcony entrances. Unfortunately, a new projection booth for the "big house" must be built at the balcony rail, at the front of the 2 balcony houses. Typically, entrance to the booth is by walking through the auditorium of one of the balcony rooms, all the way down front to a door under or at the side of the screen, opening the door, CLATTER CLATTER CLATTER for the people watching the movie. In & out, as often as people need to go into the booth to start shows, check problems, end shows, etc. It becomes an awful show in a really poor room.

The photos Bernard posted are astounding, considering the amount of engineering that must have gone into making piggyback theatres by building a whole new floor out at balcony level. Obviously, the original front end could not have been used for either room, & the remodeling was fairly complete for both as far as ceiling, walls, & floors. I would insist on arriving at that theater in a double decker bus!

As far as existing decoration goes, the decoration may or may not be consistent in scale with the front of the house at the sides under & in the balcony. Typically in big houses, architects used "zones" of decoration because the scale was neccessarily different for the perspective of people in seats on the floor in front of the balcony & seats in or under the balcony. (I think Eberson or Crane actually mentioned this in some article).

Check the scale of the sidewall decoration of the Loew's Kings; underneath the balcony it's more salon than monumental like the orchestra area. Even in the balcony, the scale is reduced (but it still is large to refer to the width of the room & the height to the ceiling).

Smaller theaters with sort of vestigial balconies have a more unified decoration scheme. All that being said, Peter's design is really the best of the swiping-space-for-another-auditorium, but still, it amounts to just building a new box in an existing space, like they did with the Egyptian/American Cinematheque. In that case, you should first look for some other available space you could just plonk a box in without destroying some existing space which is, by itself & by design, an attraction to people, which would be a stupid thing to throw away. You're trying to attract people. In show bidness, appearances are all you got.

Try to find in the building some other space in which you can construct your new box. Those spaces will likely be more easily used than carving into an auditorium.

Putting in a floor extending the balcony is fairly common over here with two cinemas splitting in this way (see links in my previous post on this thread)
One was remodeled more and was a good shape and size in the main screen with the decore being more complete. As far as I know the (repro) stage in the (extended balcony) screen could only hold 4 people at a time. The other was a more basic (and earlier) conversion which resulted in poorer shaped auditoria with a small screen in the extended balcony. Sound bleed is also an issue.

One of the converted cinemas added two screens on the stage/flytower which were accessed through a long corridor (and upstairs to the 5th screen)

Balcony theatres sometimes are quite short; front to back. I have successfully done "up/down" splits where we moved the screen wall forward 10-15 feet to allow the old front seat row to remain the front seat row. Remember we are supporting an acoustic barrier as well as the "stage" floor and screen. Louis

Layout of the Odeon Renfield Street (Paramount) Glasgow after the 1970 remodel.

The rear screen had a separate side entrance.
Since the 1970s all the screens have been subdivided further to create a 9 screen cinema. The cinema is due to close and be demolished.

The best up/down twin split I have ever seen (was) is the Loew's/United Artists in Louisville KY. This is an Eberson atmospheric that has two distinctions:

1. It opened first run: Lawrence of Arabia, 70mm so it was twinned early.

2. It was very well done. Old booth to new upper screen; new booth below new screen to old screen (D-150) Both 70mm with Ampex high level sound.

Seating is about 1100 up and about 1750 down.

In recent years the wall was removed and it is now a performing arts kind of place, completely restored except no D-150 screen.

This is where Louis started servicing projection equipment in 1971; woring for Altec Service Corp. Louis
