Almost the last sequence that we shot in The Great Bank Hoax was a restaurant scene. Halfway through this scene, or early on actually, the camera jammed. We were using a Panaflex. Usually I'm an Arriflex man, but in America sometimes it was necessary to shoot with a Panaflex for various contractual or other reasons. I didn't mind what camera I used, but with an Arriflex I can do simple maintenance myself, but with a Panaflex I didn't... wasn't able to do it. Anyway the camera jammed and it was a very serious jam, but my clapper boy, my second camera assistant said, 'Look, I used to work for Panavision and I can fix it'. So we let him fix it, which took about two hours or something. He had to get the film out, which was all bunched up inside the camera and clear the gate and refit it all together. We continued, and when we got the rushes back it wasn't... he hadn't fixed it properly. Everybody had streaks running out from their head, up or down from their chin, which meant that the shutter wasn't properly synchronised with the pull-down movement. We'd all packed our bags and we were ready to leave, so we all had to be recalled and we had to do it all again. That was an interesting lesson as to what you can and can't do, and what you can and shouldn't attempt to do yourself, and to always work on a belt and braces policy. To test everything thoroughly, in a case like that.
