THE SENTINEL opens in NY. Directed by Michael Winner. Written by Winner and Jeffrey Konvitz, from Konvitz's novel. A slumming, prestigious cast fails to circumvent the inherent schlock factor in a campy Rosemary's Baby/Exorcist redux focusing on a demonic coven's efforts to install a young model as the new guardian at the gates of hell. Cristina Raines headlines with Burgess Meredith, Martin Balsam, John Carradine, Jose Ferrer, Ava Gardner Eli Wallach and Chris Sarandon.
