Last night, I watched Peacock, a 2010 film starring Cillian Murphy, Ellen Page, and Susan Sarandon. I knew nothing about this film going in except that Murphy crossdressed in it; after his great crossdressing performance in Breakfast on Pluto, I thought I would give Peacock a look.
It was a very interesting film and held my attention from beginning to end. It really was not a film about being trans, although there are trans elements in the film that many of us can identify with.
I am not a psychologist, nor do I play one on television, so I am not sure what to call the mental condition that Murphy played in the film. I guess he had a multiple personality disorder (distinct male and a female personalities) and his deceased abusive mother was the cause.
Murphy's femulation was very good. As a female, he/she passed and none of the other characters in the film figured him/her out. In reality, I think that someone might have put two and two together, but that did not occur in this story.
One thing that bothered me about Murphy's femulation is that he/she wore male underwear (a T-shirt and briefs) under his/her female clothing. In my humble opinion, someone with his/her disorder would wear female underwear when he/she was in female mode, but that is just my opinion.
The underwear issue did not ruin the film for me and I recommend Peacock to all.
