Birdman of Alcatraz

Birdman of Alcatraz is a 1962 American biographical drama film directed by John Frankenheimer and starring Burt Lancaster. It is a largely fictionalized version of the life of Robert Stroud, who was sentenced to solitary confinement after having killed a prison guard. A federal prison inmate, he became known as the "Birdman of Alcatraz" because of his studies of birds, which had taken place when he was incarcerated at Leavenworth Prison where he was allowed to keep birds in jail. When moved to Alcatraz, Stroud was never allowed to keep any birds.
