Joel Courtney Joins Horror Film 'Mercy'

Joel Courtney steps out with Katherine McNamara at the premiere of The Impossible held at ArcLight Cinemas in Hollywood on Monday night (December 10).

It was just announced that the 16-year-old actor has joined Universal’s new horror film, Mercy, based off of the book by Stephen King.

The story revolves around two brothers (Chandler Riggs, Courtney) who go with their mother to take care of their grandma. Unbeknownst to them, the grandmother is a witch, who made an evil deal using black magic years earlier.

“Did you know that both @ChandlerRiggs & I have starred as sons of a sheriff – me in ‘Super 8′ & Chandler as the son of sheriff Rick Grimes [on The Walking Dead],” Joel tweeted of his new on-screen brother.
