The FBI arrests a serial killer John Mostow, responsible for the killing of at least 7 men. Mostow claims he was possessed by an evil spirit, a fairly common claim among serial killers as Scully points out. With Mostow in custody however, other very similar attacks occur leading Mulder to think Mostow may be telling the truth. The agent in charge of the case, the renowned Bill Patterson, doesn't think much of Mulder or the kind of cases he deals in. As the killings continue however, the evidence not only points to Mulder's theory being correct but points to the killer. Written by garykmcd

This was Kim Manners' favorite episode from Season 3. See more »


When Mostow's cell shutter is opened, the light from the corridor is extremely bright, yet when Mulder and Scully enter the cell the light is less harsh. At the bottom right of the door as it is opened a crew member's leg can briefly be seen, presumably taking the first, brighter light out of the frame. See more »

Heck of an episode, Grotesque
13 February 2010 | by beverlyhillscopseriesSee all my reviews

I have watched X-Files through the years on TV and in DVD form and I have to say this episode (Grotesque) is one of the best I have ever seen in the X-Files franchise.

I watched this episode with all the lights off and many times during this episode I jumped when scary scenes were afoot. This was a thrilling and intelligent episode that I will never forget. Kim Manners did a heck of a job with producing and directing this episode (along with Rob Bowman among others) and may he rest in peace. I wish I could have met Manners and went into detail with him about this episode.

One of my favorite parts of this episode was when Mulder went into John Mostow's studio and the camera(s) gave a sort of panoramic view of all these torso and bust statues of gargoyles. And then I loved when they got close up shots of such gargoyles. Outstanding camera work and directing.

This episode in my mind should have been a two-parter because there too much good stuff left on the cutting room floor. This was one of David Duchovny's best acting efforts of his career. Thank God he is still working and that he is currently the star of one of the better shows on TV, Californication.
