Wolfgang Müller is a top-billed German actor who has turned recognition into a durable career rather than a moment. Recognition of this size usually rests on a handful of titles, and this career is no exception. German Soldier in 'X-Men' is the role that turned into a reference point. 'Tristan & Isolde' counts among the most-seen credits. The early credits were nothing like the ones that followed. By genre, adventure leads the list.
