There should be sexual equality of nudity in films!
In 'Trance' there is a shot of Rosario Dawson, the female lead, in which we get to see her bare breasts and her genitals.
However, the most we see in terms of male nudity in this film is a shot of James McAvoy's bare back and bare bottom.
On the grounds of both gender balance and audience satisfaction, I think we should introduce a rule in movies whereby if a female actor bares all, then a male actor should do likewise, and vice versa, of course.
