From what I can see, they've made Laurie's outfit an abbreviated body suit, which makes stunt-work a lot less dicey or risque and as for Manhattan, it's all CGI and perhaps can avoid the R...but in the long run, R movies are beginning to make money at the box office, so perhaps pulling too many punches in the making of this movie would be shooting themselves in the foot. I think the built-in fanbase would be up in arms with too many changes and begin bad mouthing the whole affair.
