Star Trek fans know Bobby Clark as the Gorn who took on Captain Kirk (and lost) in the popular original series episode Arena.
Clark actually appeared more than once on Star Trek, due to his acquaintance with director Joseph Pevney. “I was in The Apple, Mirror, Mirror, The Return of the Archons and Arena,” said Clark. Arena was the first one. I got Star Trek because I’d done a lot of work on other shows with a director named Joseph Pevney. We knew each other. We got along real. He knew how I worked and so forth and so on, and I knew what he wanted and needed. When he and Gene Roddenberry talked about Arena, they of course talked about the Gorn, and Joseph knew who he wanted to play that character. When the time came, he called me in, and that was it.”
