It's rumored that the original cut presented to the MPAA received an immediate NC-17 rating (the poster art I saw a few weeks back was very suggestive of a sex assault). There will be more mutants this time out than in the original. Even Ruby will be disfigured and not a token "normal". Jupiter and Pluto are included, along with characters with self-evident names like "Big Brain", "Lizard", "Goggle", and "Cyst".
