The movies love dogs just as much as people do, and 2024 is bringing a new movie featuring an incredible pup in Arthur the King. The movie is actually based on a true story of a dog that formed an unbreakable bond with a team of adventure racers.

The dog movie is a movie genre dating all the way back to Rin Tin Tin, but in more recent years has seen hits in the form of Channing Tatum's Dog, The Art of Racing in the Rain and Dog Gone. So Arthur the King is joining a strong group of pup projects on the big screen that have won over audiences' hearts.

Before Arthur does, he is everything you need to know about the movie.

Arthur the King plot

As we said, Arthur the King is based on a true story told in the book Arthur: The Dog Who Crossed the Jungle to Find a Home by Mikael Lindnord. Here is the official synopsis of the movie from Lionsgate:

"Over the course of 10 days and 435 miles, an unbreakable bond is forged between pro adventure racer Michael Light (Mark Wahlberg) and a scrappy street dog companion dubbed Arthur. Based on an incredible true story, Arthur the King follows Light, desperate for one last chance to win, as he convinces a sponsor to back him and a team of athletes (Simu Liu, Nathalie Emmanuel and Ali Suliman) for the Adventure Racing World Championship in the Dominican Republic. As the team is pushed to their outer limits of endurance in the race, Arthur redefines what victory, loyalty and friendship truly mean."

The Arthur the King script was written by Michael Brandt.
