This is the story of an elderly Jewish doctor who lives and works in the Brooklyn slums. He is dedicated to his work and his patients. The movie revolves around his nephew's attempts to produce a documentary based on the doctor's life. The movie is ok, but Paul Muni shines. He received an Oscar nomination for this, his last role. Billy Dee Williams makes his movie debut as one of the doctor's patients. He plays a young thug with a brain tumor. He's a difficult patient and the doctor has to chase after him in order to treat him. If you look closely at the girl left on the porch in the opening scene, you'll see that it's Cicely Tyson, also an unknown at that time.
