Chinese American actor Tzi Ma has an impressively long résumé, with roles on everything from The Cosby Show to Walker, Texas Ranger. Guest appearances would be Ma's bread and butter, but the versatile actor would also cultivate a successful career in film, portraying many memorable characters in movies, like The Ladykillers. In 2005, Ma took on the recurring part of Chinese Consulate Cheng Zhi for the fourth season of the series 24, a role he would reprise for seasons five and six. ~ Cammila Albertson, All Movie Guide
