PETA Premieres Casey Affleck Film

It’s been a few years since Casey Affleck graduated from Cambridge Rindge and Latin School in Cambridge, Massachusetts, but he popped up on campus in a new video, asking everyone to be kind to cows—by dumping dairy products.

A PETA supporter wearing a cow costume showed students at Casey’s alma mater an undercover dairy farm exposé, “Dehorning: Dairy’s Dark Secret,” that the vegan actor narrated for PETA. The video shows calves and cows thrashing and crying out as they undergo intensely painful dehorning, in which farm workers gouge out or saw off the restrained animals’ sensitive horns or burn away the developing horn tissue—all without any painkillers.

Students found the cruelty in the video hard to stomach, but they loved the free boxes of rich chocolate soy milk, agreeing that it’s easy to do away with dairy products with just a few simple swaps.
