Al Pacino, is that you?

Getting into character must be an easy feat for Al Pacino. Arguably one of the greatest actors ever, Pacino is no stranger to leaving his own personality behind to take on the characters he has so famously portrayed. Characters like Michael Corleone from 'The Godfather' and his recent portrayal of Dr. Jack Kevorkian in the TV movie 'You Don't Know Jack,' which won him the Golden Globe for Best Performance by an Actor in a Mini-Series or TV Motion Picture, allow this Bronx, N.Y., native to transform from the nice guy we all imagine he is into characters that are unforgettable.

Pacino is seen here dressed as Don Quixote for the upcoming film 'Jack and Jill.' It's hard to believe just last week he was looking dapper for the Golden Globes. He is almost unrecognizable with a handlebar mustache and stark gray hair.
