Michael Peña (Crash) gives his best performance in Cesar Chavez, playing the legendary activist during his work on behalf of struggling farm workers. Unfortunately, the film is largely mediocre otherwise. A nice turn by John Malkovich gives it a little extra push, but beyond that, it’s fairly rote biopic fare. Still, for those who are unfamiliar with Chavez’ story, it’s a nice place to start, providing an overview of the man’s life and actions, as well as the conditions of migrant workers throughout the United States during the late 1960s and early 1970s. If there’s a really unfortunate thing about the movie, it’s that it just doesn’t go far enough, more or less defining Chavez by this one cause. And while it presents that case convincingly, there’s a lot more to say and probably a sturdier film to be made by including it.
