Before taking on the role of Tenoch in the Mexican blockbuster "Y tu mama tambien", nineteen-year-old Diego Luna was already a soap star his native country. After his mother's death, young Diego yearned to follow his father's footsteps into the entertainment business. A set designer on films, his father Alejando worked on set with director Alfonso Cuaron when Diego was just seven. Though Diego would eventually work for Cuaron himself as the co-star of "Y Tu Mama Tambien", the young actor would build up a strong acting resume on his own.
