for BBC radio. She played Margaret Schlegel in Lance Sieveking's adaptation of E. M. Forster's Howards End at the New Theatre in 1967. The critics found the adaptation poor, and Watford received mixed notices, rating her from excellent and the best actress in the cast to charming but shallow. Her last West End role of the 1960s was Violet Seedy in Come Sunday, half of a double-bill that ran briefly at the Fortune Theatre in October 1968. 1971–1980 In 1971 Watford toured in a revival of Maugham's The Constant Wife and the following year she was a founder-member of Robin Phillips's Company Theatre group, based at the Greenwich Theatre; fellow members included Jeremy Brett, Charles Dance, Mia Farrow, Penelope Keith and Joan Plowright. In the company's opening production, Chekhov's Three Sisters, Watford, playing Masha, was "ripely sensual", "memorable" and "the essence of Chekhovian suffering", according to critics.

The comic playing of Cole and Watford was likened by The Stage to "a superb Rolls Royce ... gliding smoothly and effortlessly along" but with "hidden power under the bonnet".

Her only cinema role of the decade was a deranged Indian servant in a horror film, The Ghoul. 1981–1994 Watford's stage roles in her later years included Monica Reed, in Coward's Present Laughter, with Donald Sinden; her portrayal
