The Kid Who Would Be King (2019) is a fantasy adventure film written and directed by Joe Cornish (Attack the Block). The movie modernizes the legend of King Arthur, weaving classic mythology into a coming-of-age story filled with magic, humor, and action. It is a fresh and heartfelt take on the timeless tale of heroism, leadership, and friendship, aimed at younger audiences but with enough charm to entertain all ages.
A New King for a New Age
Set in modern-day Britain, the story follows 12-year-old Alex Elliot (Louis Ashbourne Serkis), a kind but unremarkable boy who struggles to find his place in the world. He lives with his single mother and is frequently targeted by school bullies Lance (Tom Taylor) and Kaye (Rhianna Dorris). His only real friend is Bedders (Dean Chaumoo), a nerdy but loyal companion.
One night, while running from his bullies, Alex stumbles upon a mysterious sword embedded in a stone at a construction site. Curious, he pulls it out with surprising ease. The next day, he discovers that he has unwittingly retrieved Excalibur, the legendary sword of King Arthur.
The Return of Merlin
As news of Alexโs feat spreads, an eccentric young wizard named Merlin (Angus Imrie) appears, disguised as a teenage student at Alexโs school. He reveals that Alex is destined to fulfill an ancient prophecy and lead a new generation of knights. According to Merlin, the evil sorceress Morgana (Rebecca Ferguson) is awakening from her underground prison and will soon unleash her dark forces to enslave humanity.
At first, Alex is skeptical, but when he is attacked by Morganaโs undead warriors, called the Mortes Milles, he realizes the prophecy may be true. With no other choice, he embarks on a quest to stop Morgana before she rises to full power.
Assembling the Round Table
Realizing that he cannot face this challenge alone, Alex recruits his friend Bedders as well as his bullies, Lance and Kaye, turning them into modern versions of King Arthurโs legendary Knights of the Round Table. Together, they undergo magical training with Merlin, learning swordplay, strategy, and teamwork.
Despite their differences, the four begin to bond as they prepare for their final confrontation. They also learn valuable lessons about leadership, honor, and the importance of standing together in the face of adversity.
The Battle Against Morgana
Their journey leads them to Tintagel, the mythical birthplace of King Arthur, where Alex hopes to find answers about his destiny. Along the way, they face terrifying challenges, including illusions, magical traps, and Morganaโs ever-growing army of shadowy creatures.
As Morgana finally emerges, now in her dragon-like form, Alex and his friends must rally an army of fellow students to defend their school in an epic final battle. Using their newfound skills and courage, they engage in a thrilling fight against Morgana and her dark forces, proving that heroism is not about birthright but about bravery and selflessness.
Despite positive reviews from critics, The Kid Who Would Be King underperformed at the box office, grossing only about $32 million worldwide against a $59 million budget. However, it has since gained a following on streaming platforms and home media, where it has been appreciated as an underrated family adventure film.
Critics praised its clever writing, fun action, and heartfelt message, with many comparing its tone to classic โ80s adventure films like The Goonies or The NeverEnding Story. Parents and educators also appreciated its positive messages about teamwork, perseverance, and believing in oneself.
