The premiere of the new Pharrell Williams film was briefly disrupted by animal rights protesters at the London Film Festival on Sunday.

A screening of Piece By Piece, a biopic of the musician told through Lego, closed the festival but was postponed due to campaigners shouting and hanging banners over the balcony at the Royal Festival Hall.

They shouted “stop the torture, stop the pain,” referring to the use of animal skins and fur by fashion house Louis Vuitton, where Williams is creative director of menswear.

The singer and producer, who was on stage at the time, remained calm and applauded the activists, telling them: “God bless you.”
