There’s usually a fun element to fictionalizing history. Imagine a world where Dwight Eisenhower shot Adolf Hitler to end World War II in place of the führer’s bunker suicide, or John Wilkes Booth being stopped by a good Samaritan who saved Abraham Lincoln’s life and allowed the 16th president to deliver on his promise of “malice toward none” during Reconstruction.

Hollywood has tried its hand at historical fiction on numerous occasions. Magneto in X-Men: Days of Future Past tried to stop the bullet that killed John F. Kennedy, thus validating the magic bullet theory and that Lee Harvey Oswald acted alone. And Quentin Tarantino’s Inglorious Basterds offered an alternative history where Hitler and the entire German high command are eliminated in one massive theater fire and bombing.
