Actress Sigourney Weaver and director James Cameron (he of Titanic fame) are returning to the big screen, this time in 3-D. Sigourney has been tapped to star in Cameron's upcoming sci-fi epic, Avatar.

Her role is a botanist who is a mentor to Sam Worthington's former Marine, and she's pretty excited about the whole thing. She recently told Entertainment Weekly magazine, "When I read the script, it was such a dizzying ride that I think my jaw was permanently dropped."
