4. Tony Montana Scarface (1983)
In Brian De Palmas Scarface, Pacino gave his first glimpse of a more scenery chewing style which would come to mark some of his later work. As the actor got older, his voice certainly got LOUDER and SHOUTIER but here, the balance was still well maintained, as he uses a dubious Cuban accent to devour screenwriter Oliver Stones profane dialogue and De Palmas OTT direction, all of which revelled in 1980s Miami excess, setting a new record for the most instances of the F-bomb in one movie at the time. Widely quoted on T-shirts and posters, remade into computer games, lampooned, satirised and paid homage to in countless other films, there are so many moments in Scarface which have become part of the collective consciousness, its inconceivable not to include it in Pacinos most iconic moments.
