Al Pacino exploded onto the scene like a supernova. He landed his first leading role, in The Panic in Needle Park, in 1971, and by 1975, he had starred in four movies - The Godfather and The Godfather Part II, Serpico and Dog Day Afternoon - that were not just successes but landmarks in the history of film. Those performances became legendary and changed his life forever. 'Sonny Boy' is the memoir of a singular, special talent, whose work has stood the test of time.
