Boy Kills World release date

Boy Kills World is now playing exclusively in movie theaters in the US and UK.

That should make it a good weekend for whatever moviegoers are in the mood for, as the action of Boy Kills World is joined by the sexy drama of Zendaya's Challengers and the wholesome family movie Unsung Hero.

Boy Kills World cast

Leading the way for things is Bill Skarsgård, playing the character named Boy, who is deaf and mute and on a mission to avenge his murdered family. In addition to starring in the previously mentioned John Wick: Chapter 4, Skarsgård is also known for Barbarian, Eternals, Castle Rock and playing Pennywise the Clown in It Chapter One and Two. Skarsgård also has multiple other movies set to premiere in 2024, including The Crow and Nosferatu.

While Skarsgård’s Boy may be mute, he is not voiceless, as his internal monologue is going to be heard by the audience. That is being provided by H. Jon Benjamin, most famous for his voice work on the animated series Archer and Bob's Burger.

Rounding out the Boy Kills World cast is Jessica Rothe (Happy Death Day), Michelle Dockery (Downton Abbey), Famke Janssen (X-Men), Sharlto Copley (Monkey Man), Brett Gelman (Stranger Things), Isaiah Mustafa (It Chapter Two), Andrew Koji (Warrior) and Yaya Ruhian (The Raid).

Boy Kills World plot

With an original script written by Tyler Burton Smith and Arend Remmers, here is the official synopsis for Boy Kills World:

"Skarsgård stars as 'Boy' who vows revenge after his family is murdered by Hilda Van Der Koy (Janssen), the deranged matriarch of a corrupt post-apocalyptic dynasty that left the boy orphaned, deaf and voiceless. Driven by his inner voice, one which he co-opted from his favorite childhood video game, Boy trains with a mysterious shaman (Ruhian) to become an instrument of death and is set loose on the eve of the annual culling of dissidents. Bedlam ensues as Boy commits bloody martial arts mayhem, inciting a wrath of carnage and blood-letting. As he tries to get his bearings in this delirious realm, Boy soon falls in with a desperate resistance group, all the while bickering with the apparent ghost of his rebellious little sister."
