Love & Mercy, starring Paul Dano as 20-something Wilson in the 1960s and John Cusack as the middle-aged star in the '80s, is due for a U.S. cinema release in June (15).

The Good Vibrations hitmaker has seen preview showings of the film twice ahead of its release, but admits he will not be watching it again as it was painful to be reminded of his days as a groundbreaking songwriter and studio impresario.

Wilson tells Mojo magazine, "I said, Oh my God, I looked so energetic, y'know. And I felt depressed that now I'm 72 years old, right? So it made me remember the pep I used to have."
