Geschwister Brontë
Mason and his then wife, Pamela Kellino (Mason), had originally planned to develop a film on the Brontë family entitled "The Upturned Glass", written by Pamela and starring James as Branwell Brontë. They dropped the idea after learning of the Hollywood production "Devotion", and instead developed a psychological thriller under the same title, in which both Masons would play leading roles.
