In 1968 The Beatles unleashed Yellow Submarine, a psychotropic head-film designed to bring the world together. 50 years later, Stella McCartney calls on its message of love for a new fashion collection “It was like nothing I’d ever seen before,” says Stella McCartney, recalling the first time she saw Yellow Submarine as an eight-year-old. “The film was so ahead of its time. The animation, the psychedelic colours, the totally wacky scenes. The Blue Meanies terrified me for a long time.”
