Lionsgate has launched a heartfelt trailer for the upcoming Mark Wahlberg-led ‘Arthur The King.’

Based on a true story, the movie is set over the course of ten 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.

The story 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 cast also includes Ali Suliman, with Bear Grylls as Himself, and Paul Guilfoyle.
