Let's run through the films he wrote or co-wrote: Animal House. Meatballs. Caddyshack. Stripes. Ghostbusters. Back to School. Groundhog Day. The funniest movies from the late 70s through the early 90s. I could link to all of them, or you could just go to the Ramis page and go from there.
I've been watching a lot of Bill Murray movies this month. So I'm going to go over his body of work in the coming days, and that will include many of the movies listed above.
But for now, enjoy a couple clips from Stripes.
Great stuff, and it's aged well.
