But, in most cases, these moments of filmed history are so important, and so well known, they can be very difficult to recreate. Ultimately they need to be believable. And when scenes like the march from Selma to Montgomery and the assassination of Lee Harvey Oswald are so ingrained in history, filmmakers must go through incredible lengths to do them right. Notice how in Selma, each marcher's posture and speed and demeanour matches the actual footage, and how Portman's Jackie Kennedy stiffly backs – hands folded – into frame in the White House.
Created by UK based photographer and director Vugar Efendi, this video demonstrates the impressive attention to detail required in recreating history.
