Nimoy played an army sergeant in the 1954 science fiction thriller "Them!" and a professor in the 1958 science fiction movie "The Brain Eaters", and had a role in "The Balcony" (1963), a film adaptation of the Jean Genet play. With Vic Morrow, he co-produced "Deathwatch", a 1965 English-language film version of Genet's play "Haute Surveillance", adapted and directed by Morrow and starring Nimoy. The story dealt with three prison inmates. Partly as a result of his role, he then taught drama classes to members of Synanon, a drug rehab center, explaining: "Give a little here and it always comes back".
