[4] Scott became a leading exponent of the work of William Shakespeare through a series of notable performances in the early and mid-1930s: Cast firstly as the Player Queen and then Ophelia in Hamlet,[5] she followed this with Beatrice in Much Ado About Nothing for the Oxford University Dramatic Society.

[citation needed] In 1936 Scott was cast as Rosaline in one of the great productions of Love's Labours Lost at the Old Vic[8] and in the following year performed in more Shakespeare which included her last appearance at the Open Air Theatre until 1984 in Ring Round the Moon.

[citation needed] In addition to these classical roles, Scott's credits in contemporary drama have included the premieres of Emlyn Williams' A Murder Has Been Arranged (directed by the author in 1930), MacLeish's Panic (1936), Morna Stuart's Traitor's Gate (1938)[9] and Sidney Howard's Alien Corn (1939).

Thereafter she reprised her stage role of Leonora Stafford in the film version of the Ben Travers' Aldwych farce Dirty Work with Robertson Hare and Ralph Lynn and appeared in Herbert Wilcox's Peg of Old Drury with Anna Neagle before again joining Alexander Korda in 1936.

In addition to seasons at the Shakespeare Memorial Theatre, Stratford upon Avon in 1941 and 1942,[10] her stage credits included Clare Boothe's Margin for Error (1940), the premiere of James Bridie's The Holy Isle (1942) and the first British productions of Lillian Hellman's play Watch on the Rhine (1943)[11] and John Patrick's The Hasty Heart (1945).

Apart from world premieres of contemporary plays such as Aunt Edwina (1958) with Henry Kendall directed by the author William Douglas Home; The Right Honourable Gentleman (1964) with Anthony Quayle and Angela Huth's The Understanding (1982) with Celia Johnson and Ralph Richardson, many of her theatre credits in the 1960s, 1970s and 1980s were revivals of Oscar Wilde's comedies including Lord Arthur Savile's Crime (1968 Tour); A Woman of No Importance (1974 and 1978); The Importance of Being Earnest (1974 and The Old Vic Theatre 1980; also on television); An Ideal Husband (1976/1977 Tour) and Lady Windermere's Fan (Canada 1979).
