Frank's 1972 documentary of the Rolling Stones, "Cocksucker Blues", is arguably his best known film. The film shows the Stones on tour, engaging in heavy drug use and group sex. Frank said of the Stones, "It was great to watch them — the excitement. But my job was after the show. What I was photographing was a kind of boredom. It's so difficult being famous. It's a horrendous life. Everyone wants to get something from you." Mick Jagger reportedly told Frank, "It's a fucking good film, Robert, but if it shows in America we'll never be allowed in the country again." The Stones sued to prevent the film's release, and it was disputed whether Frank as the artist or the Stones as those who hired the artist owned the copyright. A court order restricted the film to being shown no more than five times per year, and only in the presence of Frank. Frank's photography also appeared on the cover of the Rolling Stones' album "Exile on Main St.".
