Ian Macrae Hamish Wilson was an English small role actor who appeared in over 145 films during his career. Most were small uncredited roles often playing meek public servants, professional men or busy bodies. Film appearances included The Plank 1967, The Day of the Triffids 1962, Carry On Jack 1963, Two-Way Stretch 1960, Hell Drivers 1957, The Ugly Duckling 1959 and Rotten to the Core 1965. His first film appearance was in the silent A Master of Craft in 1922, and his last was in The Wicker Man in 1973. Several of his films were made by the Boulting brothers, who considered him a "good luck charm." Wilson died in December 1987 in Devon.

The Plank is a 1967 British slapstick comedy film directed and written by Eric Sykes, and starring Sykes, Tommy Cooper and Jimmy Edwards, and featuring many of the top British comedians and comic actors of the time. It was produced by Jon Penington for Associated London Films.
