Richie Valens was one of many Mexican American pop stars of his era. Many were not known because they were members of bands and not solo artists like Valens. I thought Rosanna DeSoto gave an excellent performance as Valens' mother. She is one of my favorite actresses and can perform comedic roles equally as well as dramatic roles. She's a very versatile actress. In this movie, she was the only authentic Mexican American actor to be cast. The others were Cuban or something else. I would have preferred the role of Valens had gone to a Mexican American actor as Valens was of Mexican heritage and there are few roles about Mexican Americans that actually go to Mexican American actors. Aside from that, I enjoyed this movie.
