This gripping 1977 American thriller from Wim Wenders turns back on itself with deadly European irony. Dennis Hopper is an international art smuggler, Bruno Ganz is a Hamburg craftsman. Together they commit a murder and briefly become friends. The film has a fine grasp of tenuous emotional connections in the midst of a crumbling moral universe. Wenders’s films (Kings of the Road, Alice in the Cities) are about life on the edge; this is one of his edgiest.
