And you may have wondered about the gentle, gay-vague botanist Sergeant Dillingham, played by Walter Cartier. You may have wondered what sort of fellow changes his name from the masculine Carter to Cartier, which sounds like diamonds.
After a couple of movie roles as a dancer, he was the subject of a feature article in Look magazine. That drew the attention of Stanley Kubrick, who was looking for a "young, handsome, well-built fighter." He used Walter in his first film, Day of the Fight (1951).
Kubrick would go on to direct the homoerotic subtext-heavy Spartacus (1960) and 2001: A Space Oddysey (1968).
Afterwards Walter had a few more minor roles, as a dancer on The Benny Hill Show and Fiddler on the Roof, and a heavy on the tv series Doomwatch.
