The Brain, also known as Vengeance and Ein Toter sucht seinen Mörder, is a 1962 UK-West German co-production science fiction thriller film directed by Freddie Francis, and starring Anne Heywood and Peter van Eyck. It is adapted from the 1942 Curt Siodmak 1942 Donovan's Brain, and in this film, differing from earlier adaptations, the dead man seeks his murderer through hypnotic contact with the doctor keeping his brain alive.
