Robert Frederick Day (11 September 1922 – 17 March 2017)[4] was an English film director.
He worked his way up from clapper boy to camera operator then cinematographer while in his native country, and began directing in the mid-1950s.
His first film as director, the black comedy The Green Man (1956) for the writer-producer team of Frank Launder and Sidney Gilliat, gained good reviews.
He occasionally had small parts in his own productions, including The Haunted Strangler (1958), Two-Way Stretch (1960), and the TV mini-series Peter and Paul (1981).
In the 1970s and 1980s, Day would direct episodes of numerous American television shows, including Barnaby Jones, The F.B.I., Dallas, Walt Disney's Wonderful World of Color, and Matlock.
