The Sentinel (1976)

Synopsis
In the wake of such Satanic-themed thrillers as Rosemary's Baby, The Exorcist and The Omen comes The Sentinel. When New York fashion model (Cristina Raines) splits with her fiance (Chris Sarandon) and moves into an old brownstone, she soon discovers she has more than she bargained for in the lease. As luck would have it, a mysterious blind priest (John Carradine) who lives upstairs happens to be guarding the doorway to Hell, and she has been chosen as his replacement. Incidentally, when the door is finally opened, out spills an assortment of deformed humans whom director Michael Winner hand-picked from hospital wards and circus sideshows. ~ Jeremy Beday, All Movie Guide
