Which, by the way, Peter Lorre also did. He refused to be a part of the nazi propaganda machine and essentially told Hitler himself to fuck off. Hitler, of course, took this very poorly, and tried to have him assassinated. His name was third on a list of individuals to be repressed that was seized by the FBI off of an actual nazi secret agent during the failed nazi plot Operation Pastorius. Even today people know and caricature Lorre.
