Robert Day worked his way up from clapper boy to camera operator to full-fledged lensman in his native England before giving directing a shot in the mid-1950s. His first film as director, the black-comic The Green Man (1956) for the writer-producer team of 'Frank Launder and Sidney Gilliat, garnered fine reviews and a classic notoriety; using this as a starting point, Day went on to become one of the industry's busiest directors. He relocated to Hollywood in the 1960s and began directing scads of TV episodes and made-for-TV movies on this side of the Atlantic. He occasionally turns up in bits in his own productions, including Grip of the Strangler (1958), Two Way Stretch (1960), the mini-series Peter and Paul (1981), etc.
