This Is It, the Michael Jackson movie of cobbled-together rehearsal video and behind-the-scenes interviews, comes out on October 28, and Sony AEG is pretty sure it's going to be the biggest movie ever. Execs are estimating a $250 million take in the movie's first five days, which would shatter the current record of $204 million held by The Dark Knight. Sure, that sounds absurd, but the movie is no. 1 in ticket sales on Fandango two weeks before its release and theaters are scrambling to set up more showings. Yeah, still sounds absurd.
