Harold Ramis passed away this week, and the film world has truly lost a great mind. The actor/writer/director's mark is all over Hollywood. Ramis's longtime creative partnership with Bill Murray produced some of the best comedies of all time, including Caddyshack, Groundhog Day, and perhaps the film he's best known for, Ghostbusters. Modern-day audiences might also recognize him from his cameo in Judd Apatow's 2007 comedy Knocked Up. In case you heard the news and scratched your head, here's why you know a lot more about the famed filmmaker than you think you do.
