Tim Allen has already had a recording session for Toy Story 5. The script is "clever," says Allen.
"It’s a very, very clever story. Do you wanna do five of these? I don’t really believe it’s about the money. I’m sure they want it to be a success, but that’s not why they did it. Had they not come up with a brilliant script, they wouldn’t have done it and they wouldn’t have called me and Tom [Hanks]. It’s really clever. It was really a struggle to get, and then maybe two hours in, I was doing Buzz. I’m so blessed to be Buzz Lightyear, to be honest. It’s gonna be fun. I think we’re a year out. I’ve gotten up to the third act. We’ll do the third act. And then, we’ll go back and clean it. And then, I’ll do it about five more times. It’s a really good story, guys. It’s really good."
And here's a small glimpse of a potential plot:
"Well, I don’t know what I’m supposed to say. Yes, I just did the first five-hour session for Buzz, probably a week ago," Allen says. "It’s really, really weird to get back in it. I can’t tell you anything." Allen has returned time and again to voice Buzz Lightyear in all the Toy Story movies. His character (multiples of Buzz Lightyear actually) will be the focus of the upcoming sequel, so naturally, Allen has nothing short of praise for the upcoming sequel.
