Jack Nicholson co-wrote and co-produced The Monkees' 1968 feature film, Head.
In an interview with Mojo magazine in 2002, Bob Rafelson (one half of Raybert Productions that created The Monkees television series and who co-wrote, co-produced, and directed Head), said Nicholson remains a great fan of the film. "Jack loves Head. He still quotes lines from the film to me on a daily basis. 'Howzabout some more steam?' or 'Everybody's where they want to be.'"
In 1970, Nicholson spoke to the New York Times about Head. "Nobody ever saw that, man, but I saw it 158 million times. I loved it. Filmatically, it's the best rock 'n' roll movie ever made. It's anti-rock."
