Dark Places on AllMovie

This tepid supernatural melodrama involves the former director of a mental hospital (Robert Hardy) who inherits the estate of one of his patients -- a house which was once the site of multiple murders. He also stands to inherit a substantial sum of gold... if only he can locate the treasure, which is hidden somewhere on the premises. Before long, Christopher Lee, Joan Collins and Herbert Lom catch the scent, aiming to do a bit of prospecting themselves. As the search progresses, Hardy's mental state begins to degrade, apparently as a result of the malevolent spirits which haunt the mansion, driving him to commit murder. Despite the prominent billing of Joan Collins (at the peak of her popularity on TV's Dynasty) for the video release, she and horror stalwart Lee have rather insignificant roles in this routine thriller.
