Perhaps only the most avid of Star Trek aficionados would appreciate my delight when seeing two favorite future guests stars appearing together on Route 66, "The Man on the Monkey Board" (28 Oct. 1960 | 1.4). The above photo--my very first attempt at a screencap!--boasts Alfred Ryder (Prof. Robert Crater, "The Man Trap") in the center with Roger C. Carmel (Harcourt Fenton Mudd, "Mudd's Women," "I, Mudd," and the animated "Mudd's Passion"). Bookending the picture are Lew Ayres and series co-star Martin Milner.
While Ryder was prominently featured in the episode, this was the sole scene for Carmel, billed only as "Man in the Shower." It is notable, however, for being Carmel's first credited role. Bright futures were just ahead for both talented men.
