Eric Bana, Theo James and Jack Reynor are in talks to join the already cast Rooney Mara in Irish director Jim Sheridan's The Secret Scripture.

According to Variety, while the roles haven't yet been locked for the trio it's looking increasingly likely that James and Bana will play doctors in the mental hospital where Rooney's character is a patient, while Reynor is the love interest - a British solider.

The film is based on the novel by Sebastian Barry, and has already cast veteran actors Jeremy Irons and Vanessa Redgrave.

Sheridan last directed Dream House with Daniel Craig, and before that tackled the underrated Brothers.
