While Ella worked in menial jobs to support them, Hepburn appeared as a chorus girl in the West End musical theatre revues "High Button Shoes" (1948) at the London Hippodrome, and Cecil Landeau's "Sauce Tartare" (1949) and "Sauce Piquante" (1950) at the Cambridge Theatre. During her theatrical work, she took elocution lessons with actor Felix Aylmer to develop her voice. After being spotted by a casting director while performing in "Sauce Piquante", Hepburn was registered as a freelance actress with the Associated British Picture Corporation (ABPC). She appeared in the BBC Television play "The Silent Village", and in minor roles in the films "One Wild Oat", "Laughter in Paradise", "Young Wives' Tale", and "The Lavender Hill Mob" (all 1951). She was cast in her first major supporting role in Thorold Dickinson's "The Secret People" (1952), as a prodigious ballerina, performing all of her own dancing sequences.
