Vanity is a 1935 British comedy film directed by Adrian Brunel and starring Jane Cain, Percy Marmont and John Counsell. The plot concerns a conceited actress, convinced of the general adoration in which she is held, faking her own death in order to gratify herself by observing the depth of grief caused by her demise. However the actual reactions to the news prove to be far from what she had expected.
The film is the only known screen credit of Cain, who went on to achieve a degree of immortality in British culture after being chosen as the girl with the golden voice, becoming the original voice of the speaking clock in the United Kingdom between 1936 and 1963.
