Closed Exits is a short film based on the video game Portal originally created by Valve. The film is orientated around a young woman who signs up for medical testing but after being submitted onto the program she is kept against her will within the testing facility. She then escapes from the facility with another test subject but finds that once she has escaped everything has gone a bit to well. The film was created by a cast and crew all of which are no older than the age of 18, the film cost under 100 pounds and was shot on the canon 5D mark ii. We used abandoned places for locations including an abandoned mental asylum in Essex and an RAF base near Cambridge.
