I'm a big film buff and in their prime my faves are Nicholson, De Niro, Pacino up to Penn, Bale,Depp,Norton,Seymour-Hoffman but i think Matt Damon is an actor who doesn't make many bad films, Bourne films were exceptional but anything he is in is all the better for it The Departed, The Good Shepherd, The Talented Mr Ripley, Good Will Hunting etc. Be interested what others enjoy
