Acting career

In 1969, Norris made his acting debut in the Dean Martin film The Wrecking Crew.

In June 1970, his younger brother Wieland, a private in the 101st Airborne Division was killed in Vietnam while on patrol in the defence of Firebase Ripcord. Norris later dedicated his Missing in Action films to his brother's memory. At a martial arts demonstration in Long Beach, Norris met the soon-to-be famous martial artist Bruce Lee. In 1972 he acted as Lee's nemesis in the movie Way of the Dragon (titled Return of the Dragon in its U.S. distribution), which is widely credited with launching him toward stardom. In Asia, Norris is still known primarily for this role. In 1974, McQueen encouraged him to begin acting classes at MGM. Chuck Norris retired with a karate record of 183–10–2.

Norris' first starring role was 1977's Breaker! Breaker!, and subsequent films such as Good Guys Wear Black (1978), The Octagon (1980), An Eye for an Eye (1981), and Lone Wolf McQuade proved his increasing box office bankability. In 1984, Norris starred in Missing in Action, the first of a series of prisoner of war rescue fantasies themed around the Vietnam War POW/MIA issue that were produced by Israeli cousins Menahem Golan and Yoram Globus and released under their Cannon Films banner. Contrary to reports, Norris publicly said he was never offered the part of the Sensei of the Cobra Kai dojo in the film The Karate Kid.

Over the next four years, Norris became Cannon's most prominent star, appearing in eight films, including Code of Silence, The Delta Force, and Firewalker, in which he co-starred with Academy Award winner Louis Gossett, Jr.. Many of the aforementioned films were produced by Chuck Norris's brother Aaron, as were several episodes of Walker, Texas Ranger. In 1986, he was involved in the production of the Ruby Spears cartoon Karate Kommandos.

By the close of the 1980s, Cannon Films had faded from prominence, and Norris's star appeal seemed to go with it. He reprised his Delta Force role for MGM, which had acquired the Cannon library after the latter's Chapter 11 bankruptcy. Norris went on to make several more largely ignored films before making a transition to television. In 1993, he began shooting the series Walker, Texas Ranger, which lasted eight years on CBS and continued in heavy syndication on other channels, notably the Hallmark Channel.

On October 17, 2005, CBS premiered the Sunday Night Movie of the Week, Walker, Texas Ranger: Trial by Fire. The production was a continuation of the series, and not scripted to be a reunion movie. Norris reprised his role as Cordell Walker for the movie. He has stated that future Walker, Texas Ranger Movie of the Week projects are expected; however, this was severely impaired by CBS's 2006–2007 season decision to no longer regularly schedule Movies of the Week on Sunday night.
