Having seen 300 I know that Lena Heady isn’t exactly as, shall we say, voluptuous as the double they went with, so I assume it was for consistency. If Heady had done the second scene herself, the sudden loss of a cup size or two might have been more distracting than you think. I dunno.

I do think the second nude scene was unnecessary, especially when they had to go through the trouble of getting the double back and forking over the cash to CGI Lena’s head on her body again. They could easily have just had her, I dunno, wearing a nightgown in that scene instead.

The Walk of Shame nudity was necessary though.
