Gemma Arterton told the Sunday Times that she's scheduled to talk to director Ridley Scott about starring in the two Alien prequels he's working on. (You may know Gemma from her role as "Strawberry Fields" in the James Bond movie Quantum of Solace.)
We don't know much about the movies other than Scott's said they'll "be really tough, really nasty. It's the dark side of the moon. We are talking about gods and engineers. Engineers of space. And were the aliens designed as a form of biological warfare? Or biology that would go in and clean up a planet?"
Presumably that means Scott will be looking for a thematic replacement for Sigourney Weaver's iconic character Ellen Ripley, a new female character who's tough and capable and who isn't afraid to take charge. It was reportedly Gemma's role in the film The Disappearance of Alice Creed that attracted Scott's interest.
