A friend of mine mentioned 'Contact' was the perfect film. I thought about it for some time and found that I agree. The plot, casting, filmography, and score are all top notch.
Beyond favorite there are quite a few films I consider 'done' we don't need sequels or remakes. Most recently the original 'Willy Wonka' came to mind.
It's the American dream. What is the quote? We're all embarrassed potential millionaires?
