Manners made his mark in the science-fiction genre with his work on The X-Files, serving as producer on the landmark series from 1995 to the show's conclusion in 2002. His most recent work came as producer and director on The CW's Supernatural, even helming the episode "Family Remains," which aired just a few weeks ago.
It wasn't a strict diet of sci-fi for Manners. He also directed episodes of programs such as 21 Jump Street, Simon & Simon, Charlie's Angels, and even Baywatch.
Supernatural creator Eric Kripke released this statement regarding Manner's passing: "Everyone at Supernatural is walking around in a daze, shocked and absolutely devastated. Kim was a brilliant director; more than that, he was a mentor and friend. He was one of the patriarchs of the family, and we miss him desperately. He gave so much to Supernatural, and everything we do on the show, now and forever, is in memory of him."
You will be missed, Kim.
