Roger Holloway was a background performer in the second and third seasons of The Original Series, appearing regularly as the security officer Lemli and working as James Doohan's stand-in.
Roger Holloway joined The Original Series during its second season as a stand-in, chiefly for James Doohan, and remained with the programme until production ended in 1969.
On screen he is most often seen in a red shirt as a security guard or as a technician at a bridge or engineering station. The character acquired a name, Lemli, late in the run; he is addressed by it in Turnabout Intruder, where he is one of the guards ordered about by Janice Lester in Kirk's body.
Holloway seldom spoke on camera, but he appears in the majority of third-season episodes, guarding prisoners, manning the transporter room or standing behind the captain's chair.
