have heart. Movie film is often supplied rolled on a spool with no protection and the instructions (used to ) say to load in subdued light. The outer layer is completly fogged of course but by the third or fourth layer there is often only fog in the perforation area. So Light from the top is to be expected to only fog a couple of sheets. The New Instructions say to load in total darkness as current practice is to shoot a larger image (SUPER 16) which is more likely to be effected by fog.

Down side, Much sheet film is on Polyester base, (AKA ESTAR) which is GREAT at Light Piping, depending on the type of film that may allow some exposure on teh Bottom of the emulsion.
