Excelsis Dei

"Excelsis Dei" is the eleventh episode of the second season of the science fiction television series The X-Files. It premiered in the United States on the Fox network on December 16, 1994. It was written by Paul Brown and directed by Stephen Surjik. The episode is a "Monster-of-the-Week" story, unconnected to the series' wider mythology. "Excelsis Dei" earned a Nielsen household rating of 8.9, being watched by 8.5 million households in its initial broadcast. The episode received mixed reviews from television critics; although some complimented the episode's effects, others were critical with the way the show handled rape.

The show centers on FBI special agents Fox Mulder (David Duchovny) and Dana Scully (Gillian Anderson) who work on cases linked to the paranormal, called X-Files. Mulder is a believer in the paranormal, while the skeptical Scully has been assigned to debunk his work. In the episode Mulder and Scully are called in to investigate a claim of rape made by a nurse at a nursing home; the case falls into the purview of the X-Files due to the fact that the assailant appears to have been a disembodied spirit.

Surjik personally asked if he could direct the episode because he was a fan of the series; this was his only credit for the series. Filming the episode was difficult for the cast and crew due largely to the fact that the script arrived for the cast and crew to film only two days in advance. Other issues arose because of technical reasons; one scene required flooding a hallway with 3,300 gallons of water. Many of the scenes were filmed at Riverview Hospital, a mental health facility located in Coquitlam, British Columbia.
