American television director who directed Shore Leave, the first-season original Star Trek episode set on a planet where the crew's thoughts come to life.
Robert Sparr was a television director of the 1950s and 1960s who worked largely on westerns and adventure series, among them Lawman, Cheyenne and The Wild Wild West.
His one Star Trek episode is Shore Leave, written by Theodore Sturgeon. On an apparently idyllic planet in the Omicron Delta region, the landing party meets a white rabbit, a medieval knight, a strafing aeroplane and figures from Kirk's past, including his Academy tormentor Finnegan and his old love Ruth. The world proves to be an amusement park built by an advanced race.
Much of the episode was shot on location, with the script being rewritten during filming, and the planet was revisited in the animated episode Once Upon a Planet.
