Jim Carrey and Adam Sandler are among the funnymen who have been targeted by leading animal rights group PETA as part of a campaign to keep animals out of the movies.
Activists were appalled to see real creatures in films like Mr. Popper's Penguins and Zookeeper alongside computerized doubles and now they're appealing to the stars in person, asking them to boycott films that feature performing animals.
Letters have been sent to Carrey and Sandler as well as Steve Carell, Will Ferrell, and Ben Stiller - all of whom have starred in and/or produced films that featured wild animals.
A spokeswoman for PETA tells WENN, "Because much of the abuse suffered by the animals forced to perform in movies occurs off the set - including deplorable living and transport conditions and the use of electric prods, bullhooks, and other violent training methods - the actors are likely unaware that cruelty is routine and severe in the wild animal-training industry.
"PETA's request comes on the heels of the release of the film Zookeeper, which faced an outcry from animal protection advocates across the country after a giraffe, Tweet, suddenly collapsed and died during Zookeeper's production. The movie also features an elephant supplied by Have Trunk Will Travel, whose trainers can be seen in undercover video footage (courtesy of Animal Defenders International) beating elephants with sharp, steel-tipped bullhooks, and using electric prods to shock them."
