Colin Jeavons began a extensive association with Dickens productions on BBC Television in the late 1950’s, with 'Bleak House' as Richard Carstone, and 'Great Expectations' (for the first time) as Herbert Pocket. At the same time he played Prince Hal/Henry V in the BBC's 'The Life and Death of Sir John Falstaff'. In 1963 he portrayed the particularly reluctant hero Vadassy forced into espionage in 'Epitaph For a Spy' for once again the BBC.
In 1966 Jeavons became famous for his perfect portrayal of Uriah Heep in the BBC's 'David Copperfield'. He performed in a host of 1960s' and 1970s' TV programmes comprising of 'Doctor Who' (in "The Underwater Menace"), 'Adam Adamant Lives!' as a homicidal fashion designer, and 'The Avengers' (in "A Touch of Brimstone" and "The Winged Avenger"). Pete Stampede and Alan Hayes wrote of Jeavons in the later series as "one of those under-rated, ever-present supporting actors who never turn in a bad performance."
On kids' TV, he hosted 'Play School' for a while, and recited "The Black Vicar" on 'Jackanory'. He also appeared in the 1981 Doctor Who spin-off 'K-9 and Company’.
He performed in the 1978 Play For Today production of David Edgar's controversial 1978 play about British neo-Nazis,' Destiny'. In the same year he played the part of Mr Johnston, a schoolmaster in the BBC paranormal drama Tarry Dan, Tarry Dan, Scary old Spooky Man.
In 1979 he performed as Samson Brass in one more BBC Dickens production, 'The Old Curiosity Shop', and then in their 1981 remake of 'Great Expectations', on this occasion playing Wemmick. The same year he played a recurring UFO-obsessed eccentric in the sci-fi comedy Kinvig. His most critically celebrated role during this period was as the abandoned and abused child, Donald, in Dennis Potter's 'Blue Remembered Hills' (1979).
In the 1980s he was involved with two popular adaptations of Sherlock Holmes stories. He played Professor Moriarty in 'The Baker Street Boys' (1982), "with chilling authority" in the words of author David Stuart Davies, and "with great panache" Inspector Lestrade in the Independent Television series 'The Adventures of Sherlock Holmes’ (featuring Jeremy Brett as Holmes).
He was Briggs, the lawyer who halts the marriage between Jane and Rochester, in the 1983 BBC interpretation of 'Jane Eyre'. In 1984, he performed the existentialist philosopher Soren Kierkegaard in the 'Prometheus Unbound' episode of Don Cupitt's Sea of Faith (TV series) for the BBC. Next year he played Adolf Hitler in Hitler's SS: Portrait in Evil. In 1986 he was seen in Paradise Postponed.
He featured in the 1990 dramatization for television of 'House of Cards' by Michael Dobbs, as Tim Stamper, Tory Whip and ally of Ian Richardson's Francis Urquhart. The character returned - promoted initially to Chief Whip, then to Party Chairman - in the sequel, 'To Play the King'.
