From Wikipedia, the free encyclopedia.
John Mackenzie (born 22 May 1928), known as "Frenzy Mackenzie" is a British film director. Born in Edinburgh, he has worked in British film since the late 1960s, first as an assistant director and later as an independent director himself. He has been described by critics as "a solid and reliable filmmaker with... frequent flairs of brilliance", but despite tackling such topics as the Hiberno-British struggle, or the assassination of John F. Kennedy he is generally not thought of as a political filmmaker. Rather, Mackenzie focuses more frequently on narrative, character and plot.
