Overview
Svengali is a 1954 British drama film directed by Noel Langley and starring Hildegard Knef, Donald Wolfit and Terence Morgan, based on the 1894 novel Trilby by George du Maurier. Svengali hypnotises an artist's model into becoming a great opera singer, but she struggles to escape from his powers. It was distributed in the United States by Metro-Goldwyn-Mayer.
Donald Wolfit was a last-minute replacement for actor Robert Newton, who left three weeks into filming and can still be seen in some long shots.
Plot
After being fired from working as a barmaid in Paris bar, Trilby O'Ferrall is hired by the sculptor Durian as a model. She encounters three British painters living next door, including the sensitive Billy Bagot with whom she gradually falls in love. She also encounters the street musician Svengali, but does not much like him. Billy wants to marry Trilby, but his wealthy family do not approve. He is also distressed when he discovers her posing nude for a class of art students. He is knocked down in the street by a carriage and suffers from ill health, returning to London.
In the meantime, Svengali takes control of Trilby's life, after he is able to cure her of a headache. Despite the fact that previously she has only been able to badly sing the parlour song "Alice, Where Art Thou?" which she learnt from her Irish father, he now coaches her and transforms her into a magnificent opera singer by his mesmerising technique. She becomes an international success, performing in capitals across Europe and led by the domineering Svengali she forgets Billy completely. However, when he attends a performance of hers in London, the spell is shattered and instead of performing classical opera to the expectant crowd she sings "Alice, Where Are Thou?" in her old voice.
