Chris Rock’s stance on dog-fighting has come back to bite him in the — well, you get the picture. The comedian and documentarian behind the critically-acclaimed side-splitter Good Hair has been dumped from a upcoming biopic based on the life of late comedy icon Richard Pryor after defending convicted dog killer Michael Vick during an appearance on The Jay Leno Show earlier this month, The National Enquirer reports.

“What the hell did Michael Vick do, man? A dog, a pit bull ain’t even a real dog. A pit bull, that’s the white stuff. Dogs are white man’s best friend – dogs have never been good to black people,” Chris quipped

That didn’t go over so well with Richard’s White, animal-lovin’ widow, Jennifer Pryor

Chris had been on-board to produce the eagerly-awaited Richard Pryor: Is It Something I Said? alongside Jennifer — who just happens to be the director of the animal rescue group Pryor’s Pets. The organization, founded by Richard before his death in 2005, was created to rescue abused and neglected dogs.

“Among the 40 dogs we are currently caring for are seven pit bulls….each one is a sweet and affectionate dog who mistreated or dumped or neglected all because of their breed.”

After watching Chris’ controversial appearance on Leno, a fuming Jennifer promptly alerted her attorney that she no longer wants Chris involved in the film project.

“For your information, Chris, what Michael Vick did was to torture, drown, electrocute, and murder dogs all for fun and profit. He went to prison for felony animal cruelty! That’s what he did!” Jennifer thundered at the comic. “These types of comments only encourage abuse and misunderstanding of their breed, as well as actual dog-fighting,” she added.

The Richard Pryor biopic — which is expected to star Marlon Wayans — hits theaters in 2011.
