Man that is a hard question Wiseguy,

I do believe "Scarface" was his best non-GF role like others have said he seemed to transform into his character that he portrayed (the accent,body language,etc..)

But as Don Geoff added I was suprised that "Devil's Advocate" wasn't included. Hehis performance as the devil was outstanding acting especially the end when him and Keanu Reeves battled back and forth about good verses evil.

Let's not forget the remarkable performance of Colonel Frank Slade in "Scent of a Woman". If you didn't know anything about Al Pacino and saw that movie for the first time you'd swear he was really blind. One of the finest parts was the end when he stood before the school giving that speech about integrity and teaching the kids (our future leaders) about life and amputated spirits.

Must say if you listened to what he was saying there was a lot of truth to it.

Well I'm done babbling now someone else's turn.
