The most requested photo of the National Archives isn’t of the Constitution, the Gettysburg Address, or the Bill of Rights. It’s a picture of President Richard Nixon with Elvis Presley in the Oval Office. The comedy is based on a true story. Elvis wants to join the war on drugs. Presley and Nixon have a face-to-face complete with lovely parting gifts. If the story weren’t true, no one would believe it.

Elvis and Nixon is out in cinemas from today.
