Derek Thompson (actor)
Thompson began portraying Charlie Fairhead in "Casualty" in 1986. That same year he met his future wife, Dee Sadler, an actress playing Maggie, who had to be rescued from a cave before hospitalisation. Thompson has currently played the role of Charlie for over 30 years, and is the only remaining character from the original cast. In 2004 his character went on a six-month sabbatical, which remains his most notable absence from the show. Currently, he is allowed a few months off from filming per year. Apart from "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 last financial year.
