The Octagon (1980)

Chuck Norris shows off his martial arts chops in the quintessentially ’80s action film The Octagon (1980). Delivering every last punch and kick with an emotionless face, Mr. Total Gym stars as a tae kwon do expert who’s recruited by a beautiful businesswoman (Karen Carlson) to exterminate a band of terrorists. As Norris chops his way through swarms of bad guys, he discovers that a longtime adversary (Tadashi Yamashita) is behind the evil plot to deep-six the vixen who hired him. In the end, Chuck manages a successful mission and is rewarded by busty General Hospital star Carol Bagdasarian, whose one and only on-camera reveal occurs here.
