Mal Friedman
Mal Friedman  played redshirt Hendorff in the  second season episode . He filmed his scenes on Monday  at Desilu Stage 10.

Besides acting in children's theatre and in smaller roles on stage, Friedman worked as carpet cleaner, and was also employed by Gene Coon's wife, who brought him to the attention of her Star Trek producer husband, which resulted in his short guest spot in the series. ( Magazine Issue 283, p. 61)

This is currently his only known acting role in either television or film. However, he did lend his voice to the 1995 video game Full Throttle, as did  guest actor Hamilton Camp.
