In addition to being the first recreation of President Lincoln's assassination to be filmed at Ford's Theatre, The Persistence of Dreams is also the most historically accurate recreation to date. Courtney consulted with the nation's top experts on the Lincoln assassination, such as Richard Sloan, Harold Holzer, and Ed Steers who have each written extensively on the subject. Mike Kaufman, author of the recently published book American Brutus: John Wilkes Booth and the Lincoln Conspiracies, even gave Courtney new information about the assassination that is not yet public.
