A word of warning: the Star Wars audition footage of Harrison Ford and Mark Hamill here is ropey, to say the least. Tom Hardy's Star Trek screentest, however, is crystal clear (and handily placed next to the same scenes in finished product). And in case you were wondering who Bolaji Badejo was, he was one of the three crew members on Alien who played the xenomorph, the others being Eddie Powell and Roy Scammell. You can find out more about his only acting role here.
