Daniel Richter (born 1939 in Darien, Connecticut) is an American mime and actor who played the leader of a tribe of ape-men in 2001: A Space Odyssey.
Kubrick made him largely responsible for choreographing the "Dawn of Man" sequence, believing Richter could take the film away from Hollywood clichés of men in monkey suits.
[1] In 2002, Richter published a book about his experiences entitled Moonwatcher's Memoir: A Diary of 2001: A Space Odyssey.
[2] Richter went on to work and live with John Lennon and Yoko Ono, appearing in their 1972 Imagine video at Tittenhurst Park.
In a 2019 article at the Salon website, Richter told of how in 1969 he supplied heroin to Yoko and John Lennon while the Beatles were working in the studio.
