Last November, Pixar made the announcement Toy Story fans had been waiting for, revealing that Toy Story 4 is finally happening. Today we have word that the studio has begun casting, with Oscar-winning actress Patricia Arquette entering talks to join the voice cast. The Wrap reports that Patricia Arquette will play a laid-back hippie mother in the animated sequel, although no further character details were given.

When Toy Story 3 was released in 2010, the studio revealed that would be the final feature-length movie in the series. The voice cast did reunite several times for a number of short films and animated TV specials such as Toy Story: Small Fry, Toy Story: Hawaiian Vacation, Toy Story: Partysaurus Rex, Toy Story of Terror! and Toy Story That Time Forgot. Tom Hanks and Tim Allen are reprising their roles as Woody and Buzz Lightyear, alongside Don Rickles as Mr. Potato Head and Annie Potts as Bo Peep.

Director John Lasseter confirmed at the D23 Expo this summer that the sequel will be a love story, where Woody and Bo Peep fall for one another. The story follows Bo Peep who gets either lost or sold at a garage sale, causing Woody and Buzz to go on a mission to find her, where they run into a slew of new characters. It has also been confirmed that this will not be connected to the first trilogy, including 1995's Toy Story, 1999's Toy Story 2 and 2010's Toy Story 3, with Toy Story 4 telling a completely new story that may be expanded in forthcoming sequels.

John Lasseter is directing, with Josh Cooley serving as co-director. Rashida Jones and Will McCormack wrote the screenplay, based on a story concocted by the Pixar brain trust of Lasseter, Andrew Stanton, Pete Docter and Lee Unkrich, with Galyn Susman producing. The sequel was recently pushed from its June 16, 2017 release date to June 15, 2018.

Patricia Arquette won her first Oscar earlier this year for her performance in Best Picture nominee Boyhood. She will next be seen on the big screen in The Wannabe, arriving in theaters December 4. The actress currently stars on the hit CBS series CSI: Cyber, which debuted in midseason back in March and is currently airing its second season.
