I would agree; it's just that Scent of a Woman would have been pluperfect for Robert Duvall, who would have fitted the part so much better, IMHO. Duvall is even married to an accomplished tango dancer and could have done that part so well. Pacino's physical frame looked too small for that rank of officer.
Agreed with DuVall. A brilliant actor who never over does it … just plays the part as it should be played. Maybe that’s why he didn’t get that part that required some “over-acting” … which I thought Pacino pulled off very well. Cheers!
