Considering Rooney Mara went all out for her Lisbeth Salander transformation in The Girl With The Dragon Tattoo - getting her nipple pierced, taking up smoking, losing a bunch of weight, chopping her hair off, you'd have thought it wouldn't have been a step too far to dye her pubic hair, but apparently she had to wear a pubic wig because David Fincher was worried about the colour of her pubes. Hadn't he heard of THIS?!

As previously mentioned, we're pretty impressed with Rooney Mara's makeover - she's even admitted that she's now incorporated parts of Lisbeth into her life (ie, she's going to keep the pierced nipple), although probably not the ginger pubic wig. Talking to Metro, she revealed:

"There was a lot of discussion that went into my merkin for the movie, because I was naked quite a lot. And I don’t think a lot of people will notice all of the attention that went into that. But there was a lot of discussions around that... You know, in the book she’s meant to have strawberry-blonde hair originally and she dyes it, so we had a special merkin made that was, you know, strawberry-blonde so that it would fit. [laughs]."

She could've just borrowed Evan Rachel Wood's.

Anyway, while we're on muff watch, we'll add that Carey Mulligan's in Shame is quite a full one. No word yet on whether she used a wig. Watch this space.
