In 1912, the notorious and violent prisoner Robert Franklin Stroud (Burt Lancaster) is transferred to the Leavenworth Prison convicted for murdering a man. When a guard cancels the visit of his mother Elizabeth Stroud (Thelma Ritter) due to a violation of the internal rules, he stabs and kills the guard and goes to trial three times. He is sentenced to be executed by the gallows, but his mother appeals to President Woodrow Wilson that commutes his sentence to life imprisonment. However, the warden Harvey Shoemaker (Karl Malden) decides to keep Stroud in the solitary for the rest of his life.

One day, Stroud finds a sparrow that has fallen from the nest on the yard and he raises the bird until it is strong enough to fly. Stroud finds a motivation for his life raising and caring birds and becomes an expert in birds. He marries Stella Johnson (Betty Field) and together they run a business, providing medicine developed by Stroud. But a few years after, Stroud is transferred to Alcatraz and has to leave his birds behind.

"Birdman of Alcatraz" is an impressive film based on a true story of a prisoner that finds a purpose of life raising and caring birds and becoming a recognized ornithologist by himself. Burt Lancaster has a top-notch performance in the role of Robert Franklin Stroud and the footages with birds are impressive. However, it seems that Stroud did not have the glamour of the character performed by Burt Lancaster and was actually a psychopath. My vote is nine.

Title (Brazil): "O Homem de Alcatraz" ("The Man of Alcatraz")
