Found some video clips of Benny "the Jet" Urquidez. Legendary kickboxer who was about the only US fighter of his era who was small enough to go up against Japanese and Thai opponents instead of just beating up on other Yanks. Edited highlights of his kickboxing career here. Pity it doesn't show his trademark victory backflip but the soundtrack almost makes up for it.
He later went into films and twice fought Jackie Chan onscreen -- Wheels on Meals and Dragons Forever. But most of you are more likely to remember him duking it out with John Cusack in Grosse Point Blank.
