Some people suggested that the issue might be due to the film loop above the gate being too short. According to them, when the loop is off by even a single frame, it affects the sound of the camera. Experienced operators can often recognize this by ear – if the camera doesn’t sound right, it’s likely a pulldown issue. If the loop is too tight, the spring pressure from the pressure plate may not be strong enough to keep the film perfectly flat in the gate during exposure, which could result in uneven images. Another theory focused on the camera’s turret. Some believed that the turret wasn’t properly locked in place. Bolex cameras, they noted, are known for this issue, so it’s essential to double- check that the turret is securely locked and stays that way during operation. We’re still unsure which of these issues caused the problem. To be certain, we’d need to shoot test footage deliberately recreating both errors. However, these are definitely potential mistakes we’ll need to watch out for in the future. Fortunately, we were able to use some of the damaged footage as part of a sequence showing Mary being attacked by the two fake doctors. Unfortunately, most of the unusable footage had to be discarded. 6. Jumping images: Full frames of the jumping image sequence 61
