VOTD: 'Back To The Future' Screen Tests

/Film reader Ed C pointed me towards a couple videos which contains the original screen tests for Back to the Future. In this rare low resolution video test you can see Lea Thompson (Loraine Baines McFly), Crispin Glover (George McFly) and Thomas F. Wilson (Biff Tannen) try out lines and improv with an unknown Marty McFly stand-in. In a sequence filled with improv, George tries to get Marty to convince his mother to try out for a game show. The two videos add up to be over 18-minutes in total and can be watched now after the jump.
