If you need to kill some time watching movies or TV for free, you might want to check out Hulu.com.
The site had dozens of movies and TV shows available to watch on your computer. Think of it as the pro version of Youtube.
Some of the TV shows are currently in production, and others are old favorites. I could find gems like the entire run of Arrested Development (a favorite of mine. I didn't have to buy the DVDs) and the first two seasons of Buffy the Vampire Slayer.
The movies also include some nice surprises, from horror to Oscar-winning films.
The movies are free -- sort of. You do have to watch ads in order to see them, but that's no worse than broadcast or cable, and you can watch whatever you want whenever you want to.
