Everyone presumably understands by now that the universally praised Love & Mercy (Roadside, 6.5) is a time-flipping drama about the trials of Beach Boys maestro Brian Wilson during two stages in his life — the mid ’60s era when he created Pet Sounds and Smile and the mid ’80s when he began to slowly extricate himself from the clutches of Svengali-like therapist Eugene Landy (Paul Giamatti). Young Wilson is briliantly portrayed by Paul Dano; middle-aged Wilson is played just as compellingly by Jon Cusack. It’s interesting, therefore, that the new poster decides to use a likeness of the youngish, real-deal Wilson rather than Dano or Cusack. Which is cool — a concise way of avoiding any confusion.
