The film is the third of The Conjuring franchise, and will see Patrick Wilson and Vera Farmiga reprise their roles as paranormal investigators Ed and Lorraine Warren, who take on the Arne Cheyenne Johnson case - the first US court case in which a murder suspect claimed demonic possession as a defence.
