Initial reports suggested the actress would be joining former co-stars Bill Murray and Dan Aykroyd in a spooky new movie, 20 years after Ghostbusters II - but Weaver insisted she wasn't part of the project.
The new film will reportedly show original Ghostbusters handing over control of their spook-chasing responsibilities to a team of hot young ladies.
And Weaver now admits she will consider returning to the franchise, if she likes the follow-up.
She says, "I haven't read the script but you know, why not? I don't know any details actually but I'm looking forward to reading it. It'll be fun."
Bill Murray, Dan Aykroyd, Harold Ramis and Ernie Hudson will all be returning for the sequel, which will be directed by Ghostbusters filmmaker Ivan Reitman.
It'll be the first Ghostbusters film to hit screens in 21 years.
