No one is going to be forgetting Kristen Bell, who played the title role in the 2008 comedy movie Forgetting Sarah Marshall (about a television actress who dumps her boyfriend and encounters him later) any time soon.
She is best known to many of her fans for her work in television, appropriately enough, particularly as the title star of the teen detective show "Veronica Mars" and as Elle Bishop (for twelve episodes in the series "Heroes," about ordinary people with superhuman abilities. (Another "Heroes" star, Ali Larter, has already been featured here.)
Kristen Bell has also made a lot of movies - too many to list here. As of this writing, her most recent film is Big Miracle, which is based on the successful 1988 rescue of gray whales trapped in ice off the coast of Alaska. Ms. Bell plays a news reporter.
