1997's "Alien Resurrection" essentially closed out the "Alien" franchise story wise, leaving various questions hanging in the air. Ridley Scott's "Prometheus" answered (however vaguely) a few of those questions, as will its upcoming sequel no doubt.
Still, fans of the series have long been keen on a straight up fifth "Alien" and Sigourney Weaver getting one last outing as Ellen Ripley. As time has gone on though, that possibility has essentially gone from slim to none.
There's always hopeful optimism though, and Weaver herself appeared at the Los Angeles Times Hero Complex Film Festival over the weekend where she said she could also imagine a further sequel in the franchise being made:
"I feel after going to a couple of these Comic Cons and meeting so many fans who are so passionate about the series, passionate about Ripley — that there's more story to tell; but I don't know how to do that.
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.
There are very few filmmakers that I can think of that I would want to entrust this to. But I can think of a couple... I feel there's a longing in certain groups of fans when I meet them for the story to be finished because 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 her story.
I think that would be very satisfying at least to me — although I haven't done anything about it; but I can understand why that could happen and I certainly know young filmmakers who are interested in doing that. So we'll just have to see what happens."
Despite Weaver's desire, those in charge of the "Alien" franchise are more interested in pursuing other directions such as the "Prometheus" sequel which seems to be headed further away from its "Alien" connections.
