I reckon this place could have used Filmguard back in 1968...

That might not be too far off. When the first Star Wars released, we ran it 4 times a day for 6 months, and wore out 2 prints... roughly 360 shows per.

Image degradation wasn't what killed the prints, either... for the most part. The film between sprocket holes got brittle and eventually cracked, making the integrity of the prints unreliable.

Here is the thing. At the Uptown in DC...we regularly ran movies in excess of 400 shows and NEVER had to replace a print due to consumption. To the best of my knowledge, Star Wars, which played over a year there was the 35mm print and the 70mm print...that was it. I was not operating there at they time so I can't confirm but during my tenure, prints didn't age as has been described.

I'm curious, if you had perforation integrity problems...were you running large reels, by any chance? At the Uptown, our reels were on 22" maximum so tension would be lower than for those that ran 6000-foot reels.

Good question, Steve. We were running 2,000 foot reels in a turnkey Simplex (XL) mag/optical booth. One of the few things I don't recall is whether it was ever set up for 3D. I don't think so, as it had a single Hertner generator. I also don't recall it having clutch/pad takeups, but could be wrong about that. The booth was a union shop and was, at the time, the newest installation in that town... very well maintained. I can't imagine something as simple as excessive feed tension would be allowed up there.

I know another guy who may have worked there after I left (late '79, I think). I'll see if he remembers anything.
