Risk
This feels like a no brainer. Who wouldn’t want to go see a movie about CONQUERING THE WORLD? Risk would be epic, it would be the Dunkirk of board game movies. Ok it would actually be the entire Lord of the Rings trilogy (extended edition) of board game movies cause to truly capture Risk’s essence it would need to be 9-15 hours long and take place over many films. You’ll also have to leave the movie refusing to talk to your siblings for two weeks. Fun for the whole family!
