Slipknot's Corey Taylor to feature in Doctor Who
Slipknot star Corey Taylor's been helping Doctor Who make their latest monster that little bit scarier.
He's lent his voice (well, scream) to a new alien warlord called Fisher King.
The band were invited for a set visit when they toured Cardiff, where the show is filmed, in January.
"We needed an awesome roar for the Fisher King," Doctor Who producer Derek Ritchie explained. "We asked Corey if he might like to do the honours. He was completely up for it."
"He has one of the most well-known screams in the history of music," Derek added.
"We now have the most incredible roar for our incredible monster! He now sounds as terrifying as he looks!"
You can hear Corey's roar as Fisher King in episode four of the current series, which is set to air on 10 October.
The creature is played by the UK's tallest man Neil Fingleton and voiced by actor Peter Serafinowicz.
It's not the first bit of acting that Corey's done.
The singer starred in horror movie Fear Clinic last year, a film about a doctor who tries to cure patients' phobias using extreme methods.
Meanwhile, Jenna Coleman confirmed she was leaving Doctor Who on the Radio 1 Breakfast Show with Nick Grimshaw earlier this month.
"It will happen at some point this season," Jenna told Grimmy.
"It's been in the works for a very long time."
