This movie stars Jim Carrey and features quite a few familiar faces. It was released in 2001. I own it on DVD and have watched it a few times. Since I'm going through my DVDs to see which ones I want to sell versus keep, I'm watching this one again. I started it yesterday and had to pause it halfway through, but I'll be finishing it today. It's set during the red scare in Hollywood, and talks about WWII. I like that it's set in the past, so it's a sort of whimsical, enjoyable watch. Here's a trailer, in case anyone would like to find out more about it.
