Brothers in Law was a 1955 comedy book by Henry Cecil, himself a County Court judge, about Roger Thursby — a young barrister — experiencing his first year in chambers. In 1957 the book was made into a film starring Ian Carmichael and Terry-Thomas directed by Roy Boulting.
In 1962 Frank Muir and Denis Norden adapted the book as a television series featuring an early performance by Richard Briers in the leading role. The series also spawned a spin-off Mr. Justice Duncannon, also written by Cecil. There were also two radio adaptations, one in 1955 starring Donald Sinden, and in 1970 in which Briers reprised the role. The latter radio series ran for thirty nine episodes.
