William Louis Wallace (born December 1, 1945), nicknamed "Superfoot", is an American martial artist, former professional kickboxer, and actor.

It was PKA President, Don Quine, who coined the phrase "Superfoot" to describe Wallace after witnessing his fight first with Mark Georgantas and then with Jem Echollas.

[20] Wallace was the play-by-play commentator for the inaugural Ultimate Fighting Championship pay-per-view event UFC 1 in 1993 alongside fellow kickboxer Kathy Long and NFL Hall of Fame player Jim Brown in which he burped as he said, "Hello, I'm Bill Wallace, and welcome to McNichols Arena" in what has become a much beloved blooper from that event.

"[21] His film credits include A Force of One with Chuck Norris; Killpoint, with Cameron Mitchell; Continental Divide and Neighbors, with John Belushi; The Protector, with Jackie Chan; Los Bravos with Hector Echavarria; A Prayer for the Dying, with Mickey Rourke; Ninja Turf; and Sword of Heaven.

On March 5, 1982, Bill Wallace found John Belushi dead of a cocaine and heroin overdose, in his room in Bungalow 3, at the Chateau Marmont, on Sunset Boulevard, in Hollywood, California.

Wallace played a tough ex karate champ bodyguard (for a criminal boss), who has an extended fight scene with cop Jackie Chan in a Hong Kong warehouse.
