PETA activists protested a press screening for Piece by Piece, the animated documentary about singer, songwriter and record producer Pharrell Williams, on Saturday morning at the Toronto Film Festival.

The protesters brandished posters reading “Fur Is Dead” and “Pharrell: Stop Killing Animals for Fashion” as they urged Williams, who is also Louis Vuitton’s men’s creative director, to stop using wild animal skins and furs in his collections.

PETA campaigner Amanda Brody told The Hollywood Reporter that Williams was ignoring animal welfare concerns by using real animal fur, and alligator and snake skins in his fashion collections. “PETA doesn’t want anyone to use any sort of animal skins or furs, because anytime anyone or a brand like Louis Vuitton uses anything stolen from an animal, it means the animal endured a miserable life and a painful death,” Brody argued.

She added that Williams is ignoring faux furs and skins as humane options.
