Quite a few of them in fact.
I need to start taking the time to watch some of them.
Yep. The thing I like about films made during the Hays Code era(from the early 1930s to the mid to late 1960s when the ratings system started) is that Hollywood had to get their scripts preapproved prior to filming. Consequently, most films made prior to 1968 could be shown on TV without drastic ending.
I’d recommend films directed by Frank Capra and Howard Hawks to get started with ones made prior to 1970.
