Screenwriter Don Rhymer, whose credits included 20th Century Fox Animation’ hit Rio and the CBS comedy Evening Shade, has died. He was 51 and his longtime friend Dave Gallagher told the LA Times that Rhymer died Wednesday of cancer at USC’s Norris Comprehensive Cancer Center. One of Rhymer’s earliest credits was NBC’s Valerie. He also wrote for CBS’ Hearts Afire. He also worked on feature films, including Big Momma’s House and its two sequels, The Santa Clause 2, Agent Cody Banks 2, The Honeymooners and Sony Pictures Animation’s Surf’s Up. His TV credits also included episodes of the NBC series Caroline In The City and Bagdad Cafe. After his diagnosis three years ago, Rhymer started a blog “Let’s Radiate Don” that chronicled his treatment and his relationship with his wife and kids.
