No doubt, Pacino's best work came in the 70s when his voice wasn't scratchy and his acting was more subtle. GF I, II and Dog Day Afternoon are 3 of the greatest performances in movie history(a shame he didn't win an Oscar for a single one of these). Then there's Serpico and And Justice for All. He recieved Oscar nominations for both.

Other good post 70s performances: Scarface, Scent Of A Woman, Glengarry Glen Ross, Carlito's Way, Donnie Brasco and Insomnia.

Pacino is one of the 5 greatest actor of ALL-TIME.
