Movie Info & Cast


When bullies corner teen Alex, he grabs the first thing handy in hopes of defending himself. That object turns out to be the sword Excalibur. Drawing the sword means that Alex, played by Louis Ashbourne Serkis (son of Andy “Gollum” Serkis) is now the new King Arthur. All he has to do next is assemble his Round Table of knights, connect with Merlin, and stop the world-ending plan created by Morgan Le Fay. No problem!

Joe Cornish, who previously introduced the world to John Boyega of Star Wars fame, writes and directs this clever and rollicking revamp of the King Arthur story. The cast is a mix of young new talents and fan-favorite stars such as Patrick Stewart, who plays Merlin’s true form, and Mission: Impossible — Fallout's Rebecca Ferguson.

[An] earnest, entertaining and imaginative old-meets-new adventure.

The action is lively and quick-paced, and then suddenly over — at which point the film gets to hammer down some of its more wholesome messages.

The Kid Who Would Be King is a charming story of fantasy, pop-culture references and myth-making. It’s a movie with the playful camaraderie of “Goonies” and a few elements from ’80s sagas — like “Labyrinth,” “E.T.: The Extra-Terrestrial,” “The NeverEnding Story” and “Legend” — where young people go on character-building adventures.
