Career
McLaren worked as a stuntman and rodeo rider before being hired to appear in ads for Marlboro. In 1976, he did promotional work for the famous Marlboro cigarette advertising campaign as the "Marlboro Manitoba". After developing lung cancer in 1990, McLaren became an anti-smoking crusader citing his 30-year smoking habit as the cause of his cancer.
During the time of McLaren"s anti-smoking activism, Philip Morris denied that McLaren ever appeared in a Marlboro adjunct
In response, McLaren produced an affidavit from a talent agency that had represented him and a pay check stub asserting that he had been paid for work on a "Marlboro print" job.
