Bruno Ganz, a Swiss actor, discusses playing Adolf Hitler in the 2004 film Downfall. He took over a month to decide to accept the role, as portraying such an iconic figure was daunting. Ganz prepared extensively through research, including listening to rare recordings of Hitler speaking privately. On set, Ganz was able to get fully into character as Hitler during filming but leave him behind at other times. The physical resemblance between Ganz and Hitler surprised even Ganz himself. The film garnered praise, including from historians who knew Hitler, for the depth and accuracy of Ganz's unsettling portrayal of the Nazi leader.
