Interesting! I have the recent Shout! Factory DVD release, but I don't recall the alternate ending being present in the deleted scenes...I would have to double check. The film itself (the international version titled MONSTER) definitely features the original ending.

I've seen the film several times now, and I'm fairly confident the decapitation didn't made it back into this version. Can anyone recall when it happens? Is is when people start getting torn up at the carnival during the film's climax?

One last thing, can anybody recall if the "uncut" Japanese release is the U.S. version with the HUMANOIDS title, or the international version?
