Obviously Zombie has been working on this longer than we were led to believe. It's also likely that this film's story will be a bit less complex than that of the previous film, which will make shooting on such a short schedule easier than last time. While we're likely to see young Michael, his mom, etc. in flashbacks, it's unlikely that the film's three acts will involve three completely different periods in Michael's life the wya the last one did. This one figures to be more fo a straightforward slasher film in its structure.
