Love & Mercy

Dano alternates throughout the film between singing for real and lip-syncing to original recordings of Wilson's singing.

Spoken by Dano, the line "You think we could get a horse in here?" was taken nearly verbatim from Pet Sounds session tapes. Wilson intended to bring a horse in the studio and photograph it for the album's cover.

Dano and Cusack did not interact with each other during filming. This was encouraged by Pohlad, who didn't want the actors to simply perform an impression of Wilson, but to create their own organic understanding of his character.
