Where Did "WELCOME TO YESTERDAY" Come From?

Whoa. When was the last time the first 20 seconds of a trailer (for an original movie) immediately made you decide the movie had to be seen? Here's "WELCOME TO YESTERDAY," a Michael Bay produced scifi movie (which clearly owes more than a little to "CHRONICLE") which opens thusly: A teenager is watching a home movie of his seventh birthday and catches a glimpse of himself - as in his present-day teenage self - standing in the background.
