David and Brooklyn Beckham made quite the stylish duo when they attended the London premiere of King Arthur: Legend of the Sword [1] on Wednesday. David, who makes his acting debut [2] in the film directed by pal Guy Ritchie [3], cut a suave figure in a light brown suit, while Brooklyn kept things cool in a white t-shirt and slacks. Sadly, the rest of the Beckham brood [4] did not make it out for the event, but the pair was in good company with David's costar, Charlie Hunnam [5], who, if we're being honest, could not look any hotter in the film [6]. Victoria also gave her husband a sweet shout-out on Instagram [7], writing, "So proud of @davidbeckham! @kingarthurmovie x VB #KingArthur," alongside a clip of the movie. Check out this behind-the-scenes video [8] of King Arthur: Legend of the Sword before it hits theaters on May 12.
