Iain Johnstone obituary
Distinguished film critic for The Sunday Times who was also by turns biographer, documentary maker and television producer
… Iain Gilmour Johnstone was born in Reading in 1943, the son of Jack Johnstone, a postmaster, and his wife Ethel (née Gilmour), known as Gillie. When his father was transferred to Northern Ireland the family moved to Belfast, where he went to Campbell College…
… In 1972 Johnstone married Renate Kohler, with whom he had enjoyed an on-off relationship since university. “She suggested that getting married might stabilise it,” he wrote. He and the Countdown host Richard Whiteley, whose biography he co-wrote, were each other’s best men. The marriage was dissolved after a couple of years and he then had a relationship with Arianna Stassinopoulos, the founder of the Huffington Post, but “our romance was too good to last”. His second marriage, in 1980, was to Mo Watson, a script supervisor who survives him with their children: Sophie, who had a small part in A Fish Called Wanda; Holly, who leads a private life; and Oliver, a member of the Royal Shakespeare Company…
…Later Johnstone resumed his interest in the law, becoming a commercial mediator. His “last honest day’s work” was volunteering at the 2012 Olympic Games. Afterwards he received an engraved relay baton, which he passed to his grandson [Ralph Timothy Jack TOLLEMACHE b 2010, second in direct line to his gf 6th Baron TOLLEMACHE b 1939], who was a page of honour at the coronation of King Charles.
Iain Johnstone, film critic, was born on April 8, 1943. He died of undisclosed causes on May 4, 2023, aged 80
