When Sigourney Weaver was traveling the world promoting Avatar, she dropped a possible big spoiler about Bill Murray’s character in Ghostbusters 3. Many doubted what she said, but it looks like she was right on the money as Murray said the exact same thing to Mail Online.
The following contains spoilers you may not want to know before you see the movie.
In the December interview, Weaver said: “I know that my little son, Oscar who was kidnapped from me I think he has grown up to be a ghostbuster,” adding, “I might be in it and I see nothing wrong with being in it, although I don’t think I will have a big part in it. I think Bill Murray has a little more to do with it – he might be a ghost.”
And in the new interview, Murray says: “I’ll come back in Ghostbusters III only if I get to be a ghost. I said to them, ‘I’ll do it if you kill me off in the first reel.’ So now they are going to have me as a ghost in the film.”
