Sigourney Weaver stars as Ripley in Ridley Scott's 'Alien' - 1979

Weaver's iconic character Ellen Ripley died in the third Alien film after battling a horrific space creature in three big-budget epics. She returned for 1997's Aliens Resurrection - but opted out of two Alien Vs Predator spin-offs.

The actress wishes Scott well but insists it wouldn't be realistic for her to appear in a planned prequel.

She tells TVSquad.com, "I don't think that Ripley could appear in an Alien prequel because she doesn't have any access to the creature until the first Alien. But Ridley (Scott) is producing it and that makes me happy."
