Dark Tower is a 1987 horror film directed by Freddie Francis and Ken Wiederhorn. The prominent architect Carolyn Page (played by Jenny Agutter) is building a giant skyscraper of unparalleled scale in Barcelona, Spain. However a window washer cleaning the building falls to his death, killing a random pedestrian as well. This sparks a string of continuing gruesome accidents. Dennis Randall, a security consultant (played by Michael Moriarty) is called in to investigate the building. At first he thinks the deaths are just coincidences but soon comes to realize that a mysterious force, possibly supernatural, is at work within the giant building. Is the ghost of Carolyn's dead husband behind these murders? Randall calls in the parapsychologist Max Gold (played by Theodore Bikel) to try to track down the vicious ghost. Fans of cheesy 80s horror films would certainly be interested in watching this minor ghost film from the era.
