Nyman, who also stars in the play and will reprise his role in the film, is Professor Phillip Goodman, a psychology academic and sceptic who sees his belief in the rational tested when his old mentor, Charles Cameron, sends him a letter.
Goodman had believed Cameron dead after he disappeared 15 years ago, but he is clearly very much alive and looking for Goodman's help with three unsolved cases. Digging into the backstories, Goodman meets three haunted people who have terrifying tales to tell, and discovers that his own life might be affected.
The cameras should be rolling on this one in September and the spirits will be on the march next year. Freeman will next be seen in war comedy Whiskey Tango Foxtrot on 22 April, and Joe and Anthony Russo's Captain America: The Winter Soldier (2014) follow-up Captain America: Civil War, due here 29 April. MacKay will be part of Hulu time travel series 11.22.63 and appears in Captain Fantastic, which recently played at the Sundance Film Festival.
