 CONT: In an early fight scene at the restaurant, one of the  protection racket heavies shapes up to Lees character. Hes seen  apathetically in a boxing stance of sorts. When Lee performs a  roundhouse kick, the scene (from behind the thug) clearly shows  him with his arms behind his back and hands near/on his hips so that  the kick is delivered unchallenged. He then clearly waves his arms  forward from that position to up in the air, which creates a more  dramatic effect as to the power of the kick, i.e. knocking him that  far off balance.
