You've seen him in "Lord of the Rings" and "Star Wars," but have you heard him sing praise to the demons of Hell?
Actor Sir Christopher Lee has released a new heavy metal single called "Darkest Carols, Faithful Sing," just in time for the birth of the anti-christ.
The 92-year-old's metal work is not new, however. He released the symphonic metal album "Charlemagne: By the Sword and the Cross" in 2010 and another, "Charlemagne: The Omens of Death" in 2013.
And he's been recording music alongside his acting career since the '80s.
Last year, he released a "naughty" Christmas song called "Jingle Hell."
"It's light-hearted, joyful and fun. It's a band singing on how metal should be played, the effect it has on the band and its listeners," he says of his latest release.
