First place I saw Ganz was in Wim Wenders THE AMERICAN FRIEND, the first film adaptation of Highsmith's RIPLEY'S GAME. Dennis Hopper's Tom Ripley is kind of a cartoonish psycho cowboy (complete with Stetson), but it's Ganz's movie and he's great, much better than Dougray Scott in the equivalent role in RIPLEY'S GAME (with Malkovich as a Ripley nobody would ever trust).
