Lucki Stipetić (also Lucki Herzog) is a German film producer, and the younger half brother of filmmaker Werner Herzog. Stipetić is the official head of Werner Herzog Filmproduktion, the production company which has produced almost all of Herzog's films. Using only the above description and what you know about the world, "Lucki Herzog and Wener Herzog share the same father." is definitely correct, incorrect, or inconclusive?
