BEVERLY HILLS, Calif. (AP) — John Cusack and Paul Dano both believe the other one had the hard part in portraying Beach Boy Brian Wilson in the film “Love and Mercy.” Cusack plays Wilson in the 1980s, while Dano plays him in the 1960s. Cusack says so much film footage exists of Wilson from the 1960s, so Dano had to live up to that. Cusack says in the 1980s, Wilson shied away from the spotlight. Dano says he had the better role because he got to portray Wilson during the heyday of the Beach Boys. He says he found a great deal of joy in being in the same studio where Wilson made that music. “Love and Mercy” opens tomorrow in theaters.
