It is a bit hard ti decide, and I would say 2006 or 2008. Then again, if a 2006 movie were made, a 2007 would have to be made. If a 2008 one was made, they would have to have a segment explaining 2007 and 2006, and that would probably be at least 30 minutes, done right. Basically, all three years would have to be made movies to make sense.
