Alot of good ones, although Road to Perdition is a gem of a film and the scene mentioned with Hanks and Newman is a gret one.
I also like Paul Newman as a ne'er-do-well in the sleeper film (Nobody's Perfect?) with Bruce Willis when hes playing poker. He has won the lawyers wooden leg and the town sherrif's gun. Or the scene where he upsets his only friend, a slightly dimwitted guy, who he follows down the sidewalk in his car, until a cop arrives.
