William Alexander Murray Grigor OBE (born 1939) is a Scottish film-maker, writer, artist, exhibition curator and amateur architect who has served as director of the Edinburgh International Film Festival.

[1] In 1968, he married Barbara Grigor, née Sternschein, a teacher of French and German, film maker, exhibition curator, and chairman of the Scottish Sculpture Trust with whom he had two daughters, Sarah, b 1970 and Phoebe, b 1972.

With his wife Barbara and Peter Rush, Grigor devised the Scotch Myths exhibition, which was mounted at the Crawford Centre at the University of St Andrews in the Spring of 1981 and went on to feature in the programme of the Edinburgh International Festival.

Its exploration of popular representations of Scottish identity, notably Tartanry and the Kailyard, attracted much critical attention, influencing cultural and political debate in Scotland in the early 1980s.

"Ever to Excel" - a feature documentary with Sir Sean Connery was funded in America to mark the 600th anniversary of the University of St Andrews for its scholarship endowment campaign, and had its British premiere at the 2012 Glasgow Film Festival.

In 2008, Grigor produced seven film loops for Los Angeles' Hammer Gallery exhibition Between Earth and Heaven about the architecture of John Lautner, which coincided with the premiere of his documentary Infinite Space on the same subject.
