When an actor's resume boasts titles like The Godfather, Serpico, Dog Day Afternoon, and Scarface, he doesn't have much left to prove in our book. Yet, that doesn't mean he can habitually replay the same characters over and over again without royally pissing his old-school admirers off. Pacino still has it, evidenced in last year's HBO movie You Don't Know Jack, but he insists on sandwiching quality roles in between ones that indulge his screaming chops and tough-mentor persona.
