According to reports, her part remains unknown, however Ronan is listed alongside fellow Irish actors Aidan Turner and James Nesbitt. “Working with Peter Jackson is like working with a family,” says Hubbard, “So they’ll have a great time. Saoirse’s family will go too. Everyone is very close and very loving on those sorts of jobs. It’s not like typical studio movies at all.” Ronan previously worked with Peter Jackson in 2009’s The Lovely Bones. Production is expected to begin on the film within the coming months.
