I’ve spent the entire week searching for footage of early roles from the original Star Trek cast and discovered that Walter Koenig had an uncredited bit part on a 1963 episode of The Untouchables. However, it was also cool to discover that a young Robert Redford also had one of his earliest roles in this episode as a budding young bootlegger who intends to peddle illegal booze to a college campus. Look for Walter Koenig’s brief appearance as a college student at the 7:30 mark of this clip.
