I forgot who asked me in the shoutbox about this movie, but whomever it was, I asked my friend who was in it, and he gave me this bit of info:
"They never really filmed the end of the movie because they wrote it in as they went along. During the filming they kept saying they'd just film the end when they got to it. We'll we're done and they never filmed it! So anyway, they're going to film it and try to launch in october now, at least that's what the plan is."
The last time I spoke to him about the movie, he was still filming and according to the script the ending was to pretty much be a dejavu of the begining of the movie, as in, they start off playing a video game and at the end, they're in an action scene that mimicks the video game the movie started off with. I can't remember if he said it was a driving game or a music game, but in either case, Jack is supposed to be flying on a huge amp at one point in the movie, heh.
Here's my friend, he plays "Poops Millard" a chap who craps his pants from being rocked too hard at a D concert :P
