A new film cassette assembly comprises a thrust type cassette and a roll of a photographic film having particular properties. One such property is a low coefficient of friction between the emulsion side and back side of the film. In preferred embodiments the film has a stiffness sufficient to avoid buckling of the film when the film spool is rotated in the unwinding direction and is very thin. Most preferably, it is formed from a hydrophilic copolyester having the desired stiffness.
