Appears in Red Dragon and The Silence of the Lambs. Dr. Bloom is a renowned forensic-psychologist for the FBI. He is the only psychologist not to take any professional interest in Will Graham, for which Graham is very thankful. He helps Jack Crawford on both the cases of the Red Dragon, and Buffalo Bill. Dr. Bloom is portrayed by Paul Perri in Manhunter and is renamed Dr. Sydney Bloom, possibly to avoid confusion with real-life Professor Allan Bloom, whose book 'The Closing of the American Mind' appeared after the novel but before the film of 'Silence of the Lambs'.
