Catherine Bell has appeared in 40+ roles, mostly in TV series or TV movies, so there's little chance for any nudity.
Early-on, she was in the Brian Benben TV series "Dream On", appearing topless in that cable series. She also appeared as a nude body double for Isabella Rosselini in "Death Becomes Her".
She is best known for the TV series "JAG". There is a set of photos floating around the internet (from JAG) where she appears in a blue bikini. I didn't see that episode, but I read that the story line was her boyfriend takes her to the beach, and unbeknownst to them (or her, anyway) it is a clothing optional beach.
He suggests that she strip down, to which she replies "I'm a military officer!". He then gives her the "When in Rome..." business and tries to remove her top. Obviously that wasn't shown on TV, but there is a photo of her topless, which is either an outtake or a fake (but who cares which!)
Her movies I have seen:
*1996-2005 JAG (TV Series)
2003 - Bruce Almighty
+best bet
*would watch again
Her movies I'd like to see:
1996 - Hot Line: The Brunch Club (Showtime series)
1994 - Dream On (TV Series)
1992 - Death Becomes Her
