So, inspired by Gianna's List of 100 Movies Every Film Buff Should See, I've compiled my own list of 100 movies you may not have seen for one reason or other. I tried to stay away from AFI's top 100 films, as well as Gianna's list of recommendations. Not all are "unknown" or even "unappreciated" films, but all are worth a glance if you've missed them.
2001 - Trippy, weird, and supremely cool! Don't expect it to make sense.
28 Days Later - One of the best horror movies I've seen in a long time.
84 Charing Cross Road - A sweet, simple, completely forgotten film.
A Hard Day’s Night - A hugely influential film - and really funny (but use the subtitles!)
About a Boy - Hugh Grant gives a stellar performance here
After Hours - The best film to watch after a bad day.
All of Me - Silly, funny film from the 80s.
All Quiet on the Western Front - Early Best Picture winner, but I bet you haven't seen it!

Dogma - Kevin Smith's best, even with Linda Fiorentino and the Crap Monster.
Elmer Gantry - Burt Lancaster's hair could've won the Oscar alone.
Ferris Bueller’s Day Off - A perfectly light, fluffy confection of a movie.
