Svengali is a 1954 British drama film directed and written by Noel Langley and starring Hildegard Knef, Donald Wolfit and Terence Morgan. It was 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.
