Sideways star Paul Giamatti will play Brian Wilson's controversial therapist Dr. Eugene Landy in a new biopic of the Beach Boys singer/songwriter.

The actor, who is currently shooting The Amazing Spider-Man sequel, has signed up for Love & Mercy, according to

Landy earned the nickname Dr. Feelgood from Wilson's closest friends and associates for medicating the Good Vibrations star during 24-hour therapy sessions.

The doctor's odd methods eventually cost him his medical licence.

Paul Dano and John Cusack will play a young and older Wilson, respectively, in the film, which is set to go before cameras later this summer (13).
