Filmed in '70 or '72?
Lots of misinformation regarding this flick, but I have a hunch principle photography happened in '70, post-production finished in '72, final release in '74. Heck, even the release date fluctuates back and forth from '73 to '74! Crazy. The main reason I suspect it dates from '70 is because of James Patterson. I don't know what his professional schedule was in '70 since he was primarily a stage actor, but his health probably would've been an issue by '72. I realize younger patients can take more abuse.
