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.
