Disney fans have learned the first nugget of news out of the much-anticipated D23 Expo, Disney's biennial convention, in Anaheim, California.

Disney Chief Creative Officer John Lasseter said  "Toy Story" will be back with a fourth full-length movie, and its story revolves around Woody, a cowboy doll voiced by Tom Hanks, and Bo Peep, voiced by Annie Potts.

"It's a love story with Woody and -- and this is news -- Bo Peep," Lasseter told CNBC on Friday morning.

Lasseter said last winter that the story would revolve around Woody, but released other details on Friday, including the fact that he will be directing it.

The original "Toy Story," which was released in 1995, was the first feature-length computer-animated film. The movie and its sequels have earned approximately $2 billion at the box office, CNBC reported.

Lassiter confimred a sequel for the hit "Finding Nemo," called "Finding Dory," and a follow-up to "The Incredibles."

"At Pixar and at Disney, we only make sequels if we come up with a story that's as good or better than the original. That's our rule. We don't do things just to print money," Lasseter said.
