Before appearing in such films as Spy Kids, xXx, Once Upon A Time in Mexico and Machete or television series like Grounded For Life and Desperate Housewives, Trejo spent an 11 year span going in and out of Californiaâ€™s San Quentin prison for excessive drug addiction and armed robbery. But while in prison, he found an outlet for bottled up anger through boxing. Becoming a lightweight and welterweight boxing champion while incarcerated, Trejo embarked on a 12-step rehab program that helped him turn his life around. In 1985 he began speaking for Cocaine Anonymous, where he met a friend who later called him for a meeting. The meeting turned out to be about getting cast as an extra on the movie Runaway Train. Trejo got the part and his acting career blossomed from there.
