A film cassette may be used for housing film units of the self-developing type, each having a photosensitive area, a pod of processing fluid, and a leading edge. The film cassette may be used in a film assemblage, camera back, or imaging device having either a straight or a curvilinear film path configuration. One such film cassette includes: a chamber defined by forward and rear walls, a pair of side walls, and leading and trailing end walls; means for resiliently supporting the film units within the chamber; first spread control means for use when the imaging device has a straight film path configuration, the first spread control means including at least one projection formed on an interior surface of the forward wall; and second spread control means for use when the imaging device has a curvilinear film path configuration, the second spread control means including at least one projection formed on a bottom surface of the rear wall.
