Sigourney Weaver, 59, has ruled out any return to the Alien franchise.
Weaver, who teams up with her Aliens director James Cameron on his new film Avatar, is fed up with speculation that she is to reprise the role of alien hunter Ripley for a fifth time.
She told journalists, "I think enough already," after she was asked about her featuring in Alien 5.
She was, however, happy to talk about her new role in Cameron's sci fi flick. "I have to say I play a very dynamic character in Avatar, so it was fun to go back into space. I think it’s more satisfying to create something new."
