Re-rating is a funny thing, though. If Planet of the Apes (1968) were resubmitted, it would quite likely get a PG-13 (current rating is G) for roughly the same reason as THX got an R: nudity. As well, when The Wild Bunch was recut to the director's specifications in 1998, it was threatened with an NC-17 if it was resubmitted. Warner got around this by using the rating that was originally given to the DC in 1969 (yes folks, that's right: both the theatrical cut and the DC had the same rating). Funny how that works.
