While watching Jack Reacher I realized that Werner Herzog was playing the role of Zec. But why would such a famous arthouse director (whom I remember of not being particularly fond of classic Hollywood cinema) play a supporting role in a movie like that. Is there some interresting backstory behind this (maybe he is a fan of the books?) or was it just the usual business?
(Even if unimportant for the matter I'd like to add that oddly enough especially Zec's German synchronization (probably spoken by Herzog himself) was exceptionjally weird (not to say awfully bad).)
