Dr. Arthur Friedkin is the driving force of the Grave Encounters duology.
He is portrayed by Arthur Corber.
At the end of the movie, Lance Preston, the only one still alive, turns the camera back on after finding the secret operating room of Dr. Arthur Friedkin, who performed unethical experiments on Collingwood's patients. Lance finds pictures of the experiments, along with pictures of his team also being experimented on. He also finds evidence of satanic rituals and black magic. Lance turns around to see Friedkin performing a lobotomy on one of the team members. Lance stumbles over a skull causing Friedkin to be closer to the camera before his face turns grotesque and roars at him. Lance's screams are heard before the camera cuts out. The camera is turned back on, showing Lance alive, though his eye is bleeding from a lobotomy. He then states to the camera "I'm so much better now...finally, I can go home," before the screen cuts to black, implying that he has now gone mentally insane from his operation.
Grave Encounters 2
While Alex Wright and Jennifer wander the tunnels, they enter the surgical ward and see Dr. Friedkin's satanic altar. The lights flash on, and the pair hides. They see the doctor and his nurses bring in a patient and perform a lobotomy. The nurses then present an infant to Dr. Friedkin, who sacrifices it, draining its blood all over the patient. One of the nurses hears Jennifer's terrified whimpers. She approaches their hiding place, so the couple flees in horror only to find themselves back at the red door.
- Dr. Friedkin is arguably the true main antagonist of the series as a whole because he caused all the events in the first film and was responsible for Lance becoming insane, which led up to the events of the second film.
