Chuck Norris / The Hitman...when Chuck goes after the Arab Mafia in their restaurant he kicks the crap out of them. Classic line is when the leader (pictured) says for the "second" time that Chuck is fcking dead, Chuck quips..."You already said that." Love it.
MARS ATTACKS! / Former champ Byron Williams (Jim Brown) puts 'em up against the Martians to distract them from his pals getaway. He really kicks their ass (apparently) as he shows up at the end of the movie.
