Just to dispel all the speculation...
The platter is a Kinoton. The projectionist on when it happened is a 13 year veteran. The top plate which you can't see contained what was left of Angels and Demons. The accident occurred after the film had run completely through the projector; once through, the tension on the platter arm sitting under the plate is totally relieved and as it jolts back into it's final position, it pulls the tail of the film along at an alarmingly high speed. On very rare occasions, disastrously so as in this circumstance, the film wrapped around the platter's spine whilst still in high speed run off. Tension on the arm is re-engaged and the plate starts spinning in the opposite direction at the same high speed, and predictably, a lot film ends up on the floor, and a lot wraps tightly around the platter spine. The mess you saw occurred in around a 15 minute period.
I'd love to go into further detail, but am reluctant to. The photo you saw was sent via MMS to two people. One of those people transferred it to an email and then it appears to have exploded from there. Eventually it got back to the managing director, who was less than happy about our dirty laundry being so widely visible. I was actually a little stunned to see it posted here, but then again, I guess we're a very small community even on a worldwide basis. Needless to say, this has caused a lot of angst for several people responsible for letting the cat out of the bag.
Incidentally, the problem has been resolved by adding a projector shut-down command to the last pulse, effectively leaving the tail of the film in the gate. A simple solution, but one that often never occurs until necessity brings it about after an incident such as this.

Thanks for the feedback guys. The projector this platter runs to is on a hoist, and is usually suspended around five metres from the ground. As far as I know, it seems to be a fairly uncommon set-up so those Australians among you who do recognise the location based on that description, could you please keep it to yourselves for the moment, there is still a bit of fallout from this circulating photo!
Due to the distance of the platter from the projector, coupled with the fact that film is falling such a great height, this seems to accentuate the speed with which platter spins once tension on the arm is released. I'm not a particularly technical operator so I don't understand why the platter spins in the opposite direction once the arm is tightly re-engaged, but it does. It has happened to me once before, though I was nearby when it did. The Angels and Demons incident happened to my counterpart.
Fortunately due to the set-up of this projector, interlocking is not possible.
Thanks for the warm welcome John, and yes, platter continues spinning until physically stopped!
