Brent Forrester is an Emmy Award and Writers Guild of America award-winning American television writer. He has written for The Ben Stiller Show, The Simpsons, Mr. Show with Bob and David, King of the Hill, The Office and Undeclared.
He has a reputation for being an incredibly high-energy person. According to Greg Daniels (co-creator of King of the Hill), while Forrester was working for him, he would go through incredible lengths to get his attention. Forrester would actually make large notebooks full of pictures of lingerie models, with a few pages of notes written by Forrester asking Daniels to approve story ideas.
Forrester also showed some voice talent by doing the voice of Leon the Drug Addict in the episode of King of the Hill "Junkie Business".
