Terry Richards, a stuntman from the UK, had a uncredited role in
The Empire Strikes Back, as one of the deleted scenes Wampas; but, his most famous role was in
Raiders Of The Lost Ark, as the Cairo swordsman who is shot by Indiana Jones. While the scene originally called for a duel between him and Ford (which Richards had "trained and trained" for), Harrison fell ill, and the scene was changed.
