Try "The Hot Spot". An excellent movie and she gets nekkid.Jennifer Connelly (A Beautiful Mind / Blood Diamond)
she could be a popular actress, but i dont know anything else she's in. I love a beautiful mind and that's all i really know her from.
She's also in "Requiem For a Dream" which is probably one of the grossest and most depressing movies I've ever seen. IIRC, she does some shizz with a double dong and another girl in that one (um... yeah).
