Disney has released the first teaser trailer for Toy Story 4. In the new film, your favorite toys embark on a new adventure in Bonnie's room and introduce a new toy, Forky. The Toy Story franchise ended on a perfect note with Toy Story 3. The notion of a fourth film seems unnecessary, but they're 3-for-3 so far so why not. Toy Story 4 opens June 21, 2019.
