As an actor, Welland appeared as PC David Graham in the BBC Television seriesZ-Cars from 1962 to 1965. He was a sympathetic schoolteacher in a BAFTA-winning performance in the film Kes, and a detective in the Richard Burton film Villain. He appeared as a villain in one 1975 episode of The Sweeney, and was in the series' first cinema spin-off Sweeney! as Frank Chadwick, a newspaper editor. His other film appearances include Dennis Potter's Blue Remembered Hills as the character Willie, and Dancin' Thru the Dark. He was also in the television series Cowboys, a comedy about a dodgy builder, with Roy Kinnear. Welland's screenwriting credits include the teleplay about the strike for equal pay Leeds United, the film Yanks, starring Vanessa Redgrave and Richard Gere, which was directed by John Schlesinger, and Twice in a Lifetime, starring Gene Hackman, Ellen Burstyn and Ann-Margret. When Welland appeared on BBC Radio 4's Desert Island Discs in 1973 he said that most of his own plays "usually champion the individual against the system". He said: "I usually find that it's one man's effort to break through what is usually expected of an individual." Welland won the award for Best Original Screenplay for Chariots of Fire at the 1982 Academy Awards, and his acceptance speech included the phrase: "The British are coming!". In the film Chariots of Fire, the sign outside the Church of Scotland in Paris shows the preacher for the 9 am worship to be "C.M. Welland"; he had played a vicar in Straw Dogs. Following Chariots of Fire, he was again commissioned by David Puttnam to write the screenplay for War of the Buttons.
Death
Welland died in London in his sleep on 2 November 2015 at the age of 81. He had been afflicted with Alzheimer's disease for several years prior to his death.
Tributes
On his death, Chariots of Fire producer David Puttnam said Welland was "an unswervingly good man; a fine actor, and a seriously gifted screenwriter". Nigel Havers, who had appeared in the film, told BBC News: "I remember him being great fun with a great sense of humour and a very honest man. He had a tremendous honesty about everything he wrote. I'm just very surprised he never made more films in Hollywood. It's a great loss to us all." Z Cars co-star Brian Blessed described Welland as "a great writer and a very natural actor," adding "He had a tremendous ability for writing. He could write anything, any style."
Personal life
Welland married Patricia Sweeney in 1962, the marriage producing a son and three daughters. He was a lifelong rugby league fan who played and supported the sport, on the field and in writing newspaper columns.
