In the movie, he goes through the same experience over and over, which would be a lot less expensive to film. In mine, he’s in the Yukon for one paragraph, and then in Vietnam, and then in outer space, and so forth. The pattern’s similar. I think mine would make a better movie, but it would have a Kubrick budget.
I do recommend Source Code as an exciting movie with an engaging level of structural complexity and some really super acting. Good dialogue and dramatic in-your-face special effects. But I wish they’d done my story instead, and I was lounging in a hammock in Tahiti on my ill-gotten gains.
