Dan Aykroyd has confirmed that Bill Murray will not be a part of a third Ghostbusters film.
Speaking to Metyro, Aykroyd said the long-delayed sequel would begin production next year but Murray would not reprise his role as Peter Venkman.
"I can tell you he won't be involved," he admitted.
"It's sad but we're passing it on to a new generation. Ghostbusters 3 can be a successful movie without Bill.
"My preference would be to have him involved but at this point he doesn't seem to be coming and we have to move on. It's time to make the third one."
He added: "We've got a brilliant new writer [Etan Cohen] on it and we'll be passing the torch onto a [new] generation," he said.
"We're working on it to make it just right to satisfy our fans. I'm confident we'll be in production in the next year.
"We've got the studio on side. We've tried a few concepts which weren't right but now we've got a good structure and will make it happen."
Murray had been openly critical of previous attempts to script a third Ghostbusters film.
"You know, you just gotta have a really good script," Murray said earlier this year.
"It's hard. Even the second Ghostbusters wasn't as much fun for me as the first one. It's hard to make a sequel. It's gotta be really funny, and that first one was just so darn funny."
