Tom Hanks was quizzed on a radio show whilst promoting Larry Crowne and had this to say about the possibility of a fourth Toy Story:

"I think there will be, yeah. Yeah, yeah, think they're working on it now. There you go."

Eh, really? How many times has he been quizzed about that particular franchise whilst promoting (the not great) Larry Crowne? But during a random radio interview he lets it spill? It sounds like a reactionary answer to a question he probably wasn't really listening to. I'd be shocked if there was a fourth one. Where would they go with the story? Andy has kids?
