[6] Adrian first achieved wide public notice in a nine-month season at the Westminster Theatre from September 1938, as Pandarus in a modern dress Troilus and Cressida and Sir Ralph Bloomfield Bonnington in The Doctor's Dilemma, winning enthusiastic notices from the critics: "Mr Max Adrian triumphantly turns Pandarus into a chattering and repulsive fribble of the glossily squalid night-club type";[7] "The egregious 'B.B.'...

"[8] Adrian joined the Old Vic company in 1939, playing the Dauphin in Shaw's Saint Joan, "a beautifully malicious study in slyness, effeminacy, meanness, and a curious lost, inverted dignity.

[12] Adrian's musical numbers included "Prehistoric Complaint" (as a misfit caveman), "Excelsior" (as a put-upon Sherpa), "Guide to Britten" (as a manic conductor), "In the D'Oyly Cart [sic]" (as a jaded Gilbert and Sullivan performer), and "Surly Girls" (as headmistress of St. Trinian's).

He remained in the U.S., working in summer stock in roles as varied as Doolittle in Pygmalion, Jourdain in Le Bourgeois Gentilhomme, Shylock in The Merchant of Venice, and Sir Peter Teazle in The School for Scandal.

He played Jaques in As You Like It, Feste in Twelfth Night, Pandarus in Troilus and Cressida, the Cardinal in John Webster's The Duchess of Malfi, and Father Barré in The Devils, as well as a range of smaller parts.

[14] Adrian was one of the original members of Laurence Olivier's National Theatre Company at the Old Vic from 1963, and appeared as Polonius in the opening production of Hamlet, in which Peter O'Toole played the Prince.

The Guardian called his performance, "sly, dry, and not quite stuffy enough, but every sally from this character was touched with a look of great complicity towards the audience which made something special of this sometimes over-charged part.

[3] In the late 1960s, Adrian toured as George Bernard Shaw in the one-man show An Evening with GBS, which played in London, on Broadway, and in Asia, Africa and Australia.

He also appeared in Dr. Terror's House of Horrors (1965) as the vampire Dr Blake, The Deadly Affair (1966), and in several Ken Russell films: The Music Lovers (1970; as Anton Rubinstein), The Boy Friend (1971) and The Devils (1971).

Adrian died at age 69 from a heart attack, at his and Lister's home, Smarkham Orchard, Shamley Green, near Guildford, Surrey, after returning from the television studios where he had been recording Bertolt Brecht's The Caucasian Chalk Circle for the BBC.

[15] At his memorial service, at which the Oxford Dictionary of National Biography said the great names of British theatre paid tribute to Max Adrian's style and professionalism, the lessons were read by Alec Guinness and Laurence Olivier and the eulogy was given by Joyce Grenfell.
