Animation studio Pixar - creator of Toy Story, The Incredibles and Finding Nemo - has promised to make more original films and fewer sequels.
Three of Pixar's last four films - Toy Story 3, Cars 2 and Monsters Inc follow-up Monsters University - have been sequels. But it is aiming to focus on producing more original stories. Other past hits have included A Bug's Life, The Incredibles, Ratatouille, WALL-E and Up.
President Ed Catmull told entertainment website Buzz Feed: "For artistic reasons it's really important that we do an original film a year.
"Every once in a while, we get a film where we want or people want to see something continuing in that world - which is the rationale behind the sequel. They want those characters, which means we were successful with them. But if you keep doing that, then you aren't doing original films."
He added: "We're going to have an original film every year, then every other year have a sequel to something. That's the rough idea."
Pixar's previous sequels have been big hits, with Monsters University currently storming the US box office, and they are now working on Finding Nemo sequel Finding Dory, which is due out in November 2015.
But Ed said he and chief creative officer John Lasseter are keen to promote original ideas within the studio.
"How do you figure out how to pass the baton onto other people?" he said. "In some places they don't do that. When Walt [Disney] died, he didn't pass the baton to anybody else, and so they went downhill after that. So John and I take very seriously the fact that we need to get people up to the level where they can tell original films."
Pixar's next film, The Good Dinosaur, is due out next May. It is directed by first-timer Bob Peterson, who worked on Up, and is about a world where the dinosaurs never became extinct.
