In the childhood memories of more than one generation, Glynis Johns, who has died aged 100, will be best remembered as the Edwardian materfamilias of the hugely popular Walt Disney musical Mary Poppins (1964). Winifred Banks, married to David Tomlinson’s George W Banks, is the mother of Jane and Michael, the children in the care of the magical nanny played by Julie Andrews. A protester for the right to vote, Winifred delivers a spirited rendition of the song Sister Suffragette – “Our daughters’ daughters will adore us. And they’ll sing in grateful chorus: ‘Well done, Sister Suffragette!’” – as the children’s previous nanny tries to quit.
But the husky-voiced actor had other claims to fame from her more than 60 films and 30 stage productions. In 1973, Stephen Sondheim composed the song Send in the Clowns for Johns when she was cast in the leading role of the premiere production of his musical A Little Night Music, on Broadway. And she had won initial stardom in the British cinema as a mermaid.
In the title role of the film comedy Miranda (1948), she travels from Cornwall to London and causes romantic complications among the Chelsea set. Although the film’s whimsy may now seem strained, it was a great commercial success in its day, making Johns a top-liner in British movies. Miranda returned in a rather belated sequel, Mad About Men (1954).
By that time, Johns had moved almost completely from stage to films, where she was associated chiefly with lightweight roles, alternately fluffy and feisty. One of her most appealing opportunities came in the thriller State Secret (1950, released as The Great Manhunt in the US), playing a cabaret artiste in a fictitious Balkan country, and gamely singing Paper Doll in a wholly invented language.
It says something for her properties of youthfulness that at the age of 30 she could play a teenage schoolgirl in the melodrama Personal Affair (1953). The same year she played in two fanciful Walt Disney British productions, as Mary Tudor in The Sword and the Rose, and as the heroine wife of Rob Roy, and she went on to make her first Hollywood picture, the Danny Kaye comedy The Court Jester, in 1955. The following year she played a cameo role in the star-studded Around the World in 80 Days.
At the time Johns alternated between American and British films, generally in subordinate roles, but a rewarding one came in The Sundowners (1960), set in Australia, as a jolly barmaid who takes a shine to a visiting Englishman played by Peter Ustinov. It brought her an Oscar nomination as best supporting actress. Top billing came in a stylish horror movie, The Cabinet of Caligari (1962). She was well enough known to American audiences by this time to star in 1963 in Glynis, a TV sitcom series that ran for just one season.
In 1966 Johns returned to the London stage in The King’s Mare, as Anne of Cleves to Keith Michell’s Henry VIII. Her Welsh heritage came into play when she took the role of Myfanwy Price in a screen version of Dylan Thomas’s Under Milk Wood (1971) starring Richard Burton, Elizabeth Taylor and Peter O’Toole, and two years later came her great Broadway success as Desiree Armfeldt in A Little Night Music, which brought her a Tony award.
Glynis came from a show business background: her mother, Alice Steele (nee Wareham), was a concert pianist who performed under the name Alys Steele-Payne, and her father was the prolific character actor Mervyn Johns. He was a stalwart in particular of Ealing Studios films: father and daughter appeared together in an Ealing drama, The Halfway House (1944).
Though her vocal intonations pointed to her Welshness, Glynis was born in Pretoria, South Africa, where her parents were on tour. She was reportedly carried on to the stage at the age of three weeks, and it was not too much longer before she was appearing there in a professional capacity, making her performing debut at the Garrick theatre, London, as a dancer in a revue called Buckie’s Bears (1935).
Educated at Clifton high school, Bristol, and South Hampstead high school and the Cone School of Dancing in London, she rapidly graduated to juvenile acting roles in both theatre and cinema. Her first screen appearance came at the age of 14, as politician Ralph Richardson’s troublesome daughter in South Riding (1938), and on stage she was the young sister, another Miranda, in Esther McCracken’s comedies Quiet Wedding (1938) and Quiet Weekend (1941).
That year brought the opportunity to appear in the film 49th Parallel, starring Leslie Howard and Laurence Olivier in a spy thriller intended to bolster second world war support in the US. When the prospect of playing a mermaid came after the war, she was able to draw on her theatrical versatility: “I was quite an athlete, my muscles were strong from dancing, so the tail was just fine. I swam like a porpoise.”
Johns returned to the London stage in 1977, as Terence Rattigan’s choice to play the murderer Alma Rattenbury in his well-received dramatisation of the Rattenbury case, Cause Célèbre. Her acting appearances became sporadic, though in 1989 she starred with Rex Harrison and Stewart Granger on Broadway in Somerset Maugham’s The Circle.
She was occasionally a guest star in US television series such as Murder She Wrote and The Love Boat, and played Diane’s rich mother, Helen Chambers, in the first series of Cheers (1983) and Trudie Pepper in the sitcom Coming of Age (1988-89). By the time of her final films, While You Were Sleeping (1995) and Superstar (1999), she was a characterful grandmother.
Johns was married and divorced four times. Her first husband, from 1942 to 1948, was the actor Anthony Forwood. Their son, Gareth, also an actor, died in 2007. Marriages to two businessmen followed: David Foster, from 1952 to 1956, and Cecil Henderson, from 1960 to 1962. She was married to Elliott Arnold, a novelist, from 1964 to 1973, and is survived by a grandson and three great-grandchildren.
