During filming, Galland, who was acting as a German technical adviser, took exception to a scene where Kesselring is shown giving the Nazi salute, rather than the standard military salute. Journalist Leonard Mosley witnessed Galland spoiling the shooting and having to be escorted off the set. Galland subsequently threatened to withdraw from the production, warning "dire consequences for the film if the scene stayed in". When the finished scene was screened before Galland and his lawyer, he was persuaded to accept the scene after all.
