There's a choice quote in this Emily Browning interview over at Nylon Magazine, which was reported by Cinemablend that merits a mention. Its implications are kinda shocking. The crux is the discussion of changes that Zach Snyder had to make in order to ensure Sucker Punch (review) would win a PG-13 from the MPAA, which apparently took seven tries. I'll let Browning lay it out:
I had a very tame and mild love scene with Jon Hamm. It was like heavy breathing and making out. It was hardly a sex scene... I think that it's great for this young girl to actually take control of her own sexuality. Well, the MPAA doesn't like that. They don't think a girl should ever be in control of her own sexuality because they're from the Stone Age. I don't know what the f**k is going on and I will openly criticize it, happily. So essentially, they got Zack to edit the scene and make it look less like she's into it. And Zack said he edited it down to the point where it looked like he was taking advantage of her. That's the only way he could get a PG-13 (rating) and he said, 'I don't want to send that message.' So they cut the scene!"
