Michael Zaslow played Darnell, the first Enterprise crewman to die in a broadcast episode, in The Man Trap, and returned as Ensign Jordan in I, Mudd.
Michael Zaslow (1942–1998) became well known to American daytime audiences as Roger Thorpe in Guiding Light. Early in his career he appeared twice in The Original Series.
In The Man Trap he is Crewman Darnell, who beams down to M-113 with Kirk and McCoy. The salt creature appears to him as an alluring young woman, lures him away from the others and kills him, leaving the red mottling on his face that sets the mystery in motion. As the episode was the first to be shown, Darnell became the first of the series' many landing-party casualties.
In the second season he plays Jordan, the ensign on duty in auxiliary control who is overpowered by the android Norman at the start of I, Mudd.
