Valve has been getting plenty of great fan film renditions in honor of their games lately. First there was Escape from City 17, a short fan film created by The Purchase Brothers based on Half Life 2. This time around, it's Valve's Portal video game that's getting the treatment. Portal: No Escape is a short film directed by Dan Trachtenberg. Although he's been working on the project for a year and half, it's only in August of this year that he was able to release it. The movie focuses on what is believed to be the character of Chell (Danielle Rayne) as she wakes up and discovers that she's a prisoner. With no memory, she eventually discovers the Portal gun and uses it to escape.
