Theatre
Dotrice was a member of the Royal Shakespeare Company and in the early 1960s played a variety of roles, including Caliban in The Tempest, opposite Tom Fleming's Prospero (dir: Peter Brook), John of Gaunt and Hotspur opposite David Warner's Richard II, and Justice Shallow, opposite Hugh Griffith as Falstaff in Henry IV, and then Edward IV in the Hall/Barton-adapted Shakespeare cycle The Wars of the Roses, later broadcast by the BBC.
Dotrice played the part of John Aubrey in Brief Lives, a one-man play devised and directed by Patrick Garland in which he held the stage for almost three hours (including the interval, during which he would feign sleep). Premiering in 1967 at the Hampstead Theatre in London, the play later toured England, before two productions on Broadway. In 1968 it moved to the Criterion Theatre in the West End, where it ran for 400 performances before transferring to the Mayfair Theatre. He revived the role in 2008, again under Patrick Garland's direction.
These runs, combined with extensive international touring, earned Dotrice a place in the Guinness World Records for the greatest number of solo performances (1,782).
His other one-man productions included Mister Lincoln in 1979, and Churchill in 1982, both premiering in Washington, D.C. at Ford's Theatre.
In 1984 he starred opposite Rosemary Harris in a production of Noël Coward's Hay Fever. He appeared in the stage production of Irving Berlin's White Christmas at The Lowry theatre in Salford from November 2009 to January 2010.
