The film I recommend the most, especially if you've never seen Buster (or silent comedy in general), is Sherlock Jr. on Saturday May 21st at 7:30pm. It's simply one of the most amazing films ever made, and has been ripped off and homaged endlessly over the years by everyone from Woody Allen to Steven Spielberg to Jackie Chan. (Jackie Chan is a HUGE fan and you can see the influence in all of his films. Johnny Depp is another huge fan that comes to mind.)

PS: Don't just take my word for it about Sherlock Jr., take a look a the user reviews on the IMDB (http://www.imdb.com/title/tt0015324/usercomments).
