Hmm, I have never thought of Hoffman's type, but I have seen a lot of his movies. He seems to prefer to play slightly oddball, frenzied, somewhat stuttering but highly intelligent, intense (internal focus) characters.

Papillon, Marahton Man, Little Big Man, All the President's Men are typical of the roles he has played. He is something of an anti-hero that survives by his wits in a hostile environment; endurance and smarts rather than physical aggressive strength.

Pacino on the other hand excels in roles such as ramrod straight military officer (Scent of a woman), police officer (Heat), in your face crazed gangster (Scarface), Mafioso (The Godfather). He role figures thrive on physical violence and sensations.

I'd definitely cast Pacino as Hook in Peter Pan and not Hoffman
