After a short period as a draughtsman he joined
Theatre Workshop, then based in Manchester.
Joan Littlewood's company, also based in Glasgow for a time, then concentrated on performing its productions on tour. The company's permanent base became London's
Theatre Royal Stratford East in 1953, the opening production being
Twelfth Night with Cooper as Malvolio and
Harry H. Corbett as Sir Andrew Aguecheek. His wife, Shirley Jones (married 1955), who worked as a Theatre Workshop costume assistant, did not like his absences during the evenings, and Cooper himself found eight performances of
Billy Liar a week to be a strain. Increasingly he turned to television for work. ==Television and film career==
