ComingSoon.net got the chance to hang out with Kristen Bell ("Heroes") recently at the Turtle Bay Resort in Oahu to talk about her new comedy, Forgetting Sarah Marshall, opening in theaters on April 18. The usually conservative Bell opened up about what it was like filming an R-rated movie and what her family may think. She even talked about the dirty sex scenes she had to do with Russell Brand (they had to come up with 15 of the most obnoxious sex positions!) and shooting the opening scenes of the movie with a completely naked Jason Segel.

In the romantic disaster comedy, struggling musician Peter Bretter (Segel) has spent six years idolizing his girlfriend, television star Sarah Marshall (Bell). He's the guy left holding her purse in paparazzi photos and accidentally omitted from acceptance award speeches. But his world is rocked when she dumps him and Peter finds himself alone. After an unsuccessful bout of womanizing and an on-the-job nervous breakdown, he sees that not having Sarah may just ruin his life.

To clear his head, Peter takes an impulsive trip to Oahu, where he is confronted by his worst nightmare: his ex and her tragically hip new British-rocker boyfriend, Aldous (Brand), are sharing his hotel. But as he torments himself with the reality of Sarah's new life, he finds relief in a flirtation with Rachel (Mila Kunis), a beautiful resort employee whose laid-back approach tempts him to rejoin the world. He also finds relief in several hundred embarrassing, fruity cocktails.
