Okay, so on Youtube I found some interesting channels. They're the characters from the movie. They actually say "i am sam witwicky.." or "i am leo spitz" or whatever. i just thought it was cool because they all have cool, vids about them on their channel, and they have personal biographies for them in their description? so i was just wondering, ARE THEY OFFICIAL? anyway, check them out! its funny!
