I also read an article on the movie and in that one she said the crew was tickling her feet to ellicit an orgasmic like reaction. Since I like Brooke I prefer to believe this account, much like Winona Ryder getting her feet tickled in Bram Stoker's Dracula for the same effect. In a side to this Natalie Portman in her movie where she sleeps in the WalMart(Places in the Heart??) she said she tickled the infant's feet to make it cry, advice from her doctor father. Now I'm not posting this to advocate baby tickling, just what the article said. Natalie said she felt bad doing it but it worked. I remember a thread where someone in the business wrote about foot tickling for laughter scenes as well as sex scenes for reactions, so it's fairly common it seems. That's a good thing!!!!
