Is Al Pacino the Keith Richards of Acting?

He's 73 years old this week and the movie roles he's tackled over the last 40 years are virtually unmatched., from Michael in 'The Godfather', to Frank Slade in 'Scent of a Woman' to 'Scarface's' Tony Montana.

But the weathered face and raspy voice of Al Pacino at 73 bears little, if any, resemblance to the unlined and youthful Michael Corleone of four decades ago. Has Al aged well? Has he possibly burned the candle at both ends, as the saying goes? Take a look at Pacino now and then, and see if you don't think that over the years, Mr. Pacino has pulled more than one or two 'all-nighters'.
