The Incredible Shrinking Man (Jack Arnold, 1957). An acknowledged classic of 50s sci-fi. My memory was that the special effects were weak, and the philosophical conclusion silly. But I'm glad I gave it another watch, because I was wrong. Sure, the effects are not up to the standards of today, but they work in the context of the movie. We are regularly surprised by the gradual shrinkage of the man, and while his battles with cat and spider might be done better today, I don't think we'd do any more to improve the excitement. As for that "I still exist!" ending, it's not nearly as dumb as I remembered. Grant Williams does a fine job in the title role. The Thing from Another World and Invasion of the Body Snatchers are my two favorite 50s sci-fi movies, but The Incredible Shrinking Man isn't far behind. It's Jack Arnold's best film. #874 on the They Shoot Pictures, Don't They list of the top 1000 movies of all time.
Zombieland (Ruben Fleischer, 2009). This is an enjoyable zombie movie, with some of the feel of Edgar Wright's films. The zombies are MacGuffins ... this is actually a road movie, with Woody Harrelson playing the grownup. All four of the main cast are good (including Jesse Eisenberg, Emma Stone, and Abigail Breslin), but it's Harrelson who walks away with the film as a badass with a Twinkie obsession. There's also a great cameo ... most reviews I've read tell you who the person is, but that seems wrong in a spoiler-ish way, so on the off chance you haven't seen this nine-year-old movie, trust me, you'll like the cameo.
