Playing the title character in “The Master,” a charismatic and powerful cult leader who draws a lost WWII veteran into his life, requires an actor of command. And few are more capable of holding attention without being overly theatrical than Hoffman. His Lancaster Dodd rarely needs to raise his voice to make a point, and a pointed glare often speaks volumes. Dodd is full of contradictions; a family man with a wandering eye, he seems truly to want to do good while also being in complete control of others. That Hoffman finds the humanity in such a man is an accomplishment.
