This Could be Sir Ian McKellen's Scariest Role Ever

Sir Ian McKellen surely has one of the most distinctive voices in TV, film, and theater: when he speaks, it's pretty difficult not to give him your full attention. So it's intriguing to hear that the legendary thesp has decided to lend his rich, gravelly tones to one of the scariest characters in the pop culture canon: The Exorcist's demon.

McKellen will provide the voice of the demon in the upcoming West End production of The Exorcist, The Stage reports. The play is based on the original William Peter Blatty novel of the same name, which was famously adapted into a hugely successful 1973 movie starring Ellen Burstyn and Linda Blair.

The London production of The Exorcist will debut at the Phoenix Theatre on October 20, and you can book tickets right up until March 10, 2018. So get planning your U.K. vacation now!

Though McKellen perhaps isn't immediately associated with the horror genre, one of his most acclaimed film roles has roots in this world. In 1999, he earned his first Oscar nomination for his performance as James Whale — director of horror classics Frankenstein and The Invisible Man — in the excellent biopic Gods and Monsters.

And if you're wondering when you might see him on screen again, don't worry! He's also been cast in an upcoming, modern-day movie reimagining of Hamlet titled Hamlet Revenant. According to Deadline, his co-stars will include Wonder Woman's Connie Nielsen and The Usual Suspects' Gabriel Byrne. We're looking forward to seeing the first trailer already.
