Alan Wheatley was an English actor and former radio announcer. He is perhaps best known for playing the Sheriff of Nottingham in the 1950s TV series The Adventures of Robin Hood, with Richard Greene playing Robin Hood. In 1951, Wheatley had played Sherlock Holmes in the first TV series about the fictional detective, but no recordings of it are known to exist.
Wheatley starred as Sherlock Holmes in the 1951 BBC TV series, which was the first such series though not the Holmes character's first appearance on television. The programme aired live for six episodes, and apparently no recordings were made. In the later Robin Hood series, Wheatley appeared regularly as the Sheriff in the first three seasons; in the fourth and final season, his role was mostly taken over by that of the Deputy Sheriff (John Arnatt) as a result of Wheatley's departure from the series. He also had roles in Danger Man and The Avengers. Wheatley played the first character to be killed on-screen by a Dalek in Doctor Who, when he appeared as Thal leader Temmosus in the 1963–64 serial The Daleks.
His film credits include: Caesar and Cleopatra (1945), The Rake's Progress (1945), Brighton Rock (1947), Calling Paul Temple (1948), The Pickwick Papers (1952), Spaceways (1953), Simon and Laura (1955), A Jolly Bad Fellow (1964) and Tomorrow at Ten (1964) among others. He also appeared in Inn for Trouble (1960), a film spin-off of the TV comedy The Larkins.
