Lost reels?
According to trivia I've read elsewhere, the rather weird plot pacing and non-sequitor cuts to scenes shot elsewhere with other actors was due to the fact that a substantial amount of film "in the can" was actually *lost* right after filming was done, and other footage was tacked on and edited in to get the run time up over an hour.
The two scenes with Franklin (at his house at the begining, at the hospital later) are some of the funniest sex scenes in *any* movie.
