Alvy Ray Smith
Smith and Catmull co-founded Pixar in 1986 with financing from Steve Jobs. After the spinout from Lucasfilm of Pixar, he served on the board of directors and was executive vice president. According to the Steve Jobs biography "iCon" by Jeffrey S. Young and William L. Simon, Alvy Ray quit Pixar after a heated argument with Jobs over use of a whiteboard. It was an unwritten rule that none other than Jobs was allowed to use it, a rule Smith decided to break in front of everyone after Jobs went "total street bully" on him and they ended up screaming into each other's face "in full bull rage". Despite being the co-founder of Pixar, Young and Simon claim that the company has largely overlooked his part in company history since his departure. For example, there is no mention of Smith on the Pixar website.
Brenda Chapman
Chapman moved to Pixar in 2003, where she had a brief stint on "Cars" before beginning development on and directing "Brave". Chapman conceived the project and was announced as the director of the film, making her Pixar's first female director. In October 2010, however, she was replaced by Mark Andrews following creative disagreements. There were rumors that she subsequently left Pixar, but she remained on staff until shortly after the release of "Brave", and started work as a consultant at Lucasfilm at the end of July 2012, where she helped solve story problems of "Strange Magic". When asked whether she will return to Pixar, Chapman responded: "That door is closed. I made the right decision to leave and firmly closed that door. I have no desire to go back there. The atmosphere and the leadership doesn't fit well with me." She has stated a sequel to "Brave" is inevitable.
