In 1938, she was featured opposite Robert Donat and Rosalind Russell in The Citadel. She appeared in two of the British-made Alfred Hitchcock films, Young and Innocent, (1937) playing a nightmare of an aunt who demands that everyone enjoy themselves at her young daughter's birthday party, and The Lady Vanishes, (1938) in which she played a sinister baroness; two vastly different characters.
