The film follows Hannah (Hall), a widow struggling to accept the death of her husband, whose biography she is currently attempting to write. She meets New York academic Andrew (Sudeikis), who has a differing opinion on the life and death of her husband, and the two begin to collaborate.
Rose Byrne had been announced as the co-lead when the project was first reported in April 2013.
Hall is currently starring in a revival of Machinal on Broadway. Her credits on the London stage include Mrs. Warren's Profession, which earned her the Ian Charleson Award in 2003, As You Like It (Ian Charleson-nominated), Man and Superman, The Fight for Barbara, Galileo's Daughter, Don Juan, A Winter's Tale (Ian Charleson Award), The Cherry Orchard (Evening Standard Theatre Award nomination) and Twelfth Night, directed by her father, Sir Peter Hall.
Hall received a Golden Globe Award nomination for "Vicky Cristina Barcelona." Her film credits also include "Iron Man 3," "Lay the Favorite," "The Awakening," "The Town," "Everything Must Go," "Please Give," "Dorian Gray," "Frost/Nixon," "The Prestige" and "Starter for 10," which marked her feature-film debut.
