Just watched UltraViolet........yes she has an ass, it got more screen time than her face...not really sure what the movie was about though. Seemed to just be a reason to put her in tight pants and show every possible scene from behind and between her legs.
ULTRAVIOLET is a mess, which is a pity since that movie got fucking chopped up by the studio.
40+ minutes were cut out, the planned FX never finished, and FOX had a dud on its hands.
