Sigourney Weaver has revealed that she would like to film a fifth Alien movie.
The Hollywood actress said that she feels there is "more story to tell" with her character Ellen Ripley, following 1997's Alien: Resurrection.
The Jean-Pierre Jeunet movie was followed by the non-canon Alien vs Predator films and Ridley Scott's prequel Prometheus.
Speaking at a Q&A following a screening of Alien and Aliens at the Hero Complex Film Festival, Weaver said: "I feel there's a longing in certain groups of fans when I meet them for the story to be finished... We really left it up in the air and I feel a bit badly about that, because I was part of that decision-making process.
"I didn't want to make four and five in a bundle. I think it's hard to make these films all in a big lump. You need time to sort of let things resonate, so I can imagine a situation where we could at least finish telling [Ellen's] story."
Speaking about a fifth movie's possible plot, she said: "I don't think Alien belongs on Earth popping out of a haystack, which is where I was afraid it was going to go. I feel it should take place in the far reaches of the universe, where no-one in their right mind would go."
Weaver also said that there were "very few" people she would entrust a sequel to.
She added: "I certainly know young filmmakers who are interested in doing it. I haven't done anything about it, but it could happen, and I think that would be very satisfying, at least to me."
The cast of Aliens recently reunited after 28 years for a fan convention in Calgary.
Ridley Scott's Prometheus sequel is scheduled to be released in 2016.
