A number of actors have been added to the cast of Francesca Gregorini’s (Tanner Hall) indie Emanuel and the Truth About Fishes. The film stars Kaya Scodelario (Clash of the Titans) as a troubled 17-year-old named Emanuel who agrees to babysit her new neighbor Linda’s “baby”, though the baby turns out to actually be a life-like doll. “She goes along with the delusion while befriending Linda (Jessica Biel), who happens to be the splitting image of Emanuel’s late mother.” Now Alfred Molina (Spider-Man 2), Frances O’Connor (A.I. Artificial Intelligence), Jimmi Simpson (Date Night), and rising star Aneurin Barnard are set to join the cast. Hit the jump for more.

Variety reports that Molina will play Emanuel’s father, O’Connor will play her stepmother, Simpson will play one of her co-workers, and Barnard will take on the role of her love interest. Rooney Mara was originally set as the title character, but was forced to drop out due to scheduling conflicts. Gregorini spoke with Variety a bit about the tone of the pic:

"Lars and the Real Girl is an easy comparison, but it veers away from that tonally. I consider it a psychological drama-thriller, with comedic elements. ... It deals with death, salvation and redemption, as well as the lengths we'll go to to deny our own mortality. It's about the secrets we tell ourselves and keep from each other, and how intricate those lies are."

The director also admitted that she didn’t initially seek out Biel for the supporting role, but the actress blew her away with her audition. “I’m excited for people to discover this side of her,” she added. Production is set to get underway later this month in Los Angeles.
