The Caretaker

"...Dr. Albert Caine [AKA, '"The Caretaker"] is a tall and dark man with a large black top hat, black tuxedo suit, a skull-like face, and long dark-gray hair...Once a well-respected surgeon, he became the caretaker of the Shady Oaks Cemetery in Willamette Valley. Caine later converted the Victorian-style mansion he and his family lived in into a mortuary/funeral parlor. For years during his career as a surgeon, Dr. Caine was intensely interested in the workings of the body and what happened to the patients he couldn't save, what happens to a person when they die...

...While [he] may have been passionate about saving lives, by the end nothing could be further from the truth. From the slipshod way he conducted his experiments, it was clear that Dr. Caine himself had little belief that he was doing serious work. The Caretaker ran little more than a butcher shop; the major surgery without anesthesia was proof of that. His diaries showed that he was a doctor who had gone mad with the power he had over the dead, then his living patients. In his vanity, he fancied himself as a pioneer in his self-styled field of research, and in spite of the horrors in the back rooms, took a measure of pride in keeping up the appearances of a professional funeral director...

[He]is an icon for Universal Studios Halloween event called "Halloween Horror Nights". He was the main icon, aka the Big Bad, of its twelfth year in 2002, known as "Halloween Horror Nights: Islands of Fear"...During Halloween Horror Nights 23 in 2013, he and fellow icon Jack the Clown sported cameo appearances in The Cabin in the Woods haunted house, based off the film of the same name..."
