How much of the movies is really how it happened?A fun and illuminating look at cinema's mistreatment of history by acclaimed historian and Guardian writer Alex von Tunzelmann. From ancient Egypt to the Tudors to the Nazis, the film industry has often defined how we think of the past. But how much of what we see on the screen is true? And does it really matter if filmmakers just make it all up? In this talk illustrated with film clips, Alex von Tunzelmann takes a comic look at the history of the world as told through the movies, the good, the bad and the very, very ugly.
