This 1979 Werner Herzog film starring Klaus Kinski is just one of the film versions of the Georg Büchner play, first performed in 1913.
More on Klaus Kinski can be found in the post on Aguirre – he had a stellar performance in Woyzeck! His wife in this film, Marie, is played by Eva Mattes, who won at Cannes for this supporting role.
The Captain is played by Wolfgang Reichmann, who has been in many film versions of plays. From Othello to Der zerbrochene Krug, from Nathan der Weise to König Ödipus – the list goes on.
Due to the nature of the plot, there are some scenes of sexual content which may not be appropriate for all levels. Skipping or editing may be an option, but it may change the ability to understand the main character’s downfall or the violent response to his wife.
