Bishop García Diego High School. He has modeled for
Ralph Lauren,
Gianni Versace,
Calvin Klein, and Doug Ordway early in his career. In the 1990s he was one of the top male models. As an actor, he is best known for portraying Johnny Domino, the lead character in the 1997–1999 television series
Night Man, and Agent Thompson, the assassin who kills
Trinity at the climax of
The Matrix Reloaded (2003). He also appeared as
Vick Chamberlain, a T-888 Terminator in the television series
Terminator: The Sarah Connor Chronicles (2008). McColm also portrayed the henchman of
Jason Statham in the 2004 film
Cellular. McColm has a black belt in
Kenpo Karate, but its cast received some praise. Writing for
Ultimate Action Movies, Andrew Babcock opined that McColm "had the it factor," and "gave a very likable performance." He was named "the new action star of the 90s" by the International Producers' Association (IPA). Robert W. Welkos of
Los Angeles Times declared that McColm might be "Hollywood's next generation action star," following in the footsteps of Arnold Schwarzenegger and
Sylvester Stallone. In 1997 he appeared in the lead role in the Jack Gill-directed film
The Protector. Portraying Kenneth James Conway, an ex-commando and a private detective, he had a chance to impress the audiences with both his martial arts skills and a perfect musculature. In a review for
The Unknown Movies McColm's role was summarized positively: "He looks good, shows that he knows a fair bit about martial arts, and he does seem to be putting some effort in his performance." The same year he also starred in a low-budget action movie
Fight and Revenge, which is believed to be
lost nowadays. In 1999 the actor filmed his scenes for the
Clint Eastwood-directed adventure drama
Space Cowboys. He portrayed the
U.S. Air Force navigator named "Tank" Sullivan as a young man, while
James Garner played his older self. The movie was released in August 2000 to positive critical reception. He was set to return as Agent Thompson in
The Matrix Resurrections (2021), although his character never appeared in the final film. He was set to star as a lead in a
Jack Abramoff-produced, 25 million dollars-costing action–adventure movie called
An Act of Courage. It was supposed to be filmed in Malaysia in 1992. ==Filmography==
