The unrated version has about ten more minutes
of added footage, though I couldn't see that any of it helped.
But
it added the footage is «not conclusive».
Update:
added footage for Sword Fight.
There is an unrated version of the movie being released, but I have serious doubts that
the added footage will improve the movie much, if at all.
I like the fact viewers can see
the added footage separate from the Unrated edition.
In a nice touch I've not before encountered, the Blu - ray (reviewed here) gives you the chance to watch the unrated cut with
an added footage marker (an apple graphic, appropriately enough) designating where the movie is changed from its original theatrical release.
Finally, the end credits are extended to cover
the added footage.
