No matter what the documentary wants you to believe, you’ll never be Arnold Schwarzenegger

You know you’re big when the director and producers of a three-part Netflix documentary on your life think your first name is recognizable enough to be the title. “Arnold’’ is the story of Arnold Schwarzenegger, and “big’’ is the theme.

Part 1 is “Athlete,’’ in which we see how a boy in Austria grew into a ridiculously muscled bodybuilder. Part 2, “Actor,’’ deals with Schwarzenegger’s box-office domination as an action hero. Part 3, “American,’’ tells the story of his rise to governor of California.
