Different perf sizes ( Cine ) on polyester based films, through film camera's....I don't think so......

Where is you sense of adventure Simon..
Movie Negative and other CAMERA films are traditionally on Acetate base. LAB and PRINT films are on Poly base.
While the perfs ARE different, and even the spacing is slightly different, it should not upset a typical STILL camera. You might have problems running Still Film through a movie camera. The difference in spacing is 4 ten-thousands of an inch per perf, and you don't know how much old still film has shrunk.
The Bell and howel perfs are also a tiny bit smaller, but as the original Leica was made to use movie film, I would imagine that most cameras if they use the sprockets for advance can accommodate the Bell and Howell perfs.
I know I have not had an issue, even with my old roll of 200 feet of ILFORD Pan-F movie film I bought out of date a couple of years after it was discontinued. Only funky thing with that is the Wording "Ilford Safety FIlm" that reads correctly from the EMUSION side (which makes very good sense for the way that movies were edited by hand)
Yes - Caution is needed, and the only colour Movie stock that can be used for still Shooting without a lot of hassle are the ektachrome stocks. (I forget if the 64 was ever made in 35mm)
