Road to Perdition - Do people forget that Tom Hanks, Paul Newman AND Jude Law were in a film together? Yeah, yeah, Daniel Craig was in it but he wasn't anything special, nor was he Bond yet. Still, a great period film from the Prohibition Era.
Lock, Stock and Two Smoking Barrels - This is probably a cult favorite now, but because it is that means it was originally overlooked. It is a great, English film for a debut director and has a great cast.
The Straight Story - A tale of an old man who travels cross country on a lawn mower to make amends with his brother before one of them dies. Filled with so much symbolism and messages, this beautiful film is the least liked by David Lynch fans.
