Toy Story 2 was almost an entirely different movie (produced by Disney, not Pixar) before a complete overhaul.
That’s almost exactly 17 months from today; not long for any major production, and practically a blink when it comes to complex computer animated movies like the ones made by Pixar.
Variety reports that Stephany Folsom has been hired as the latest writer on Toy Story 4.
Lasseter was originally attached as the co-director of the film; last summer, he stepped away from the project as well.
