I agree that the FMC only shows a few good films a month when they could show many more--such as pre-1935 Fox films that exist. FMC will show a film several times in a month. However, they are pretty good about showing their Cinemascope films in their original ratio.
FYI Spencer: I've seen Up the River on FMC; however, the print wasn't very good--it was scratchy and some frames must have been missing as it jumped around quite a bit. Considering Spencer Tracy made a number of films at Fox, FMC has only shown Up the River, Dante's Inferno and Me and My Gal.
