Early life
Thompson was born in and is from Belfast and has a twin sister. During their teenage years, they combined to form the singing duo Elaine and Derek. They recorded four albums and 15 EPs together, singing in harmonies, and released one eponymously titled album on the Parlophone label in 1961. They then formed the folk trio Odin's People with Larry Johns, and recorded two singles in 1967.
Career
Thompson appeared in the feature film Gonks Go Beat (1965).
From 1976, he appeared in many early productions at the National Theatre, London's new South Bank home.
In the late 1970s and early 1980s, Thompson became a regular face in BBC and ITV dramas. Appearances include Softly, Softly, Play for Today, and Rock Follies of 77. He got a big break in Harry's Game, in which he played the lead IRA gunman on the run following the assassination of a government minister. Later, he played another IRA hitman in the TV series The Price and for a British mercenary gang in the Wild Geese II (1985).
During the same period, Thompson had minor film roles in Yanks (1979) and Breaking Glass (1980), and played Jeff, Harold Shand's lieutenant, in the film The Long Good Friday. Before Thompson appeared in Casualty, he had a recurring role, as DS Jimmy Fenton, in the ITV police drama The Gentle Touch, and played William Thurley in Channel 4's Brookside in 1983.
Casualty
Thompson began portraying Charlie Fairhead in Casualty in 1986. The following year, he met his future wife, Dee Sadler, an actress playing the role of Maggie in an episode of the show's second series, a potholer who had to be rescued from a cave before hospitalisation. Thompson played the role of Charlie for more than 30 years, and was the last remaining character from the original cast until his departure on 16 March 2024. In 2004, his character went on a six-month sabbatical, which was his most notable absence from the show. In his latter years with the programme, he was allowed a few months off from filming each year.
Apart from in Casualty, he has also played Charlie in the spin-off shows Holby City and HolbyBlue. It was revealed in July 2017 that Thompson was the BBC's highest-paid actor, earning between £350,000 and £400,000 over the previous financial year. In 2023, it was announced that, after 38 years, Thompson would be leaving Casualty; his exit aired in March 2024, at the conclusion of a special two-part episode. In 2026, Thompson made a brief return to the role to celebrate the fortieth anniversary of Casualty.
Family
As of 2010, Thompson and his wife, Dee, lived in a rented flat in Bristol; they also own a house in Brixton. The couple have a son, who appeared as a baby in one 1990 episode of Casualty, as the son of regular character Duffy, and he also has an older son by a previous marriage to Christine, a theatre director.
A sufferer of dystonia, Thompson became patron of the Dystonia Society in 2006.
