The Octagon Trivia

When Richard Norton (as "Long Legs", not Kyo) is kicked in the Groin by Chuck Norris, he grabs himself and yelps out "Oh shit... shit!". Norton himself said that when he was assisting with the stunts on the set of "The Blues Brothers" and told John Belushi the fight he'd be in, Belushi was the one who told him to say "Oh shit!" when getting kicked in the groin.
Fighting Stars Magazine ranked the climactic fight between Chuck Norris and Tadashi Yamashita as #13 on their list of the 25 greatest fight scenes of all time.
