The Simpsons co creator Sam Simon passed away earlier this week. To celebrate his life, Fusion is airing Rebel with a Cause: The Sam Simon Story, a documentary the two parties made to showcase Simon's work with his Sam Simon Foundation. Fusion was given the rights to document the final months of Simon's life back in August.

“Our hope is to pay tribute to his life and career while also sparking an important conversation about animal rights and empowering young people to be a catalyst for change,” said Fuson CEO Isaac Lee when the project was announced last summer.

Rebel with a Cause: The Sam Simon Story will air Sunday at 8 PM.
