Wow, lots of people like some of my favorite movies - but there's no way I can pick just one.... here's a 'short' list - no particular order...
Paint your wagon and Coogan's Bluff - mainly because I have my own personal Clint Eastwood lookalike (well, back when the movies were made anyway) in fact, DH was called "Coogan" by quite a few people like they were the only ones who discovered the fact LOL
Parent Trap (only the original) has always been one of my all time favorites along with The Trouble with Angels - I have a scathingly brilliant idea...
The Indiana Jones movies, and the original three Star Wars
Some of my favorite comedies:
Clue, That old Feeling (I LOVE Bette Midler) Down Periscope, My Fellow Americans, Support Your Local Sheriff, The Villain
Just a small sample...
