20ish Movies for a Desert Island

I was browsing Corey Marion's blog, catching up on the inner lives of the peeps at IconFactory, and saw that a number of their crew have posted their lists of top 20 movies to have on a desert island, plus a few guilty pleasures. The lists, to my mind, are like comfort food for the eyes, and it reminds me of some good ole' days back in grad school when I watched Ged cut together video excerpts from some of his favorite movies into one seamless sequence. Ged, Corey, and Anthony Piraino have all posted their lists publicly, with the kind of personable commentary you'd expect from the nice guys at IF. I haven't made my list yet, but don't let that stop you from enjoying theirs! To start, I'd probably pick Ratatouille (really close to my soul in a lot of ways, saw it 3 times practically back to back) and The Last Starfighter as a guilty pleasure (early 3D computer graphics, arcades games, and high camp space opera, oh yeah!)
