As everyone knows, I like myself a good fan-made film based on my favourite computer games. This Left 4 Dead inspired film goes from zero to awesome in the last three minutes. I love it!
When Portal was first produced I had a feeling that if it would prove to be a successful game it would see a film inspired by it. As far as I know there's no film being planned just yet, even after the commercial success of Portal 2, but it has already inspired Portal: No Escape, a seven-minute fan film that knocks the socks off many Hollywood productions. Check it out.
