This is a far cry from the hot soccer player who was named People’s Sexiest Man Alive back in 2015. Beckham has been one of the world’s biggest sex symbols for years. So why did he go for such an ugly makeover?

“It’s in my contract that I must be the most beautiful person on screen,” Beckham's co-star Charlie Hunnam joked to E! News. “So I said, ‘David Beckham ain’t waltzing up here with those baby blues and those chiseled cheekbones. Throw a scar on him or I’ll be in my trailer!’”

Hunnam added that Ritchie wanted Beckham’s new look to remain hidden until the film came out. “We’d play half the scene and Beckham would be all scarred up and maybe you wouldn’t realize it was him and then he would turn around and it would be the big reveal,” he said

Well, the cat’s out of the bag now. You can only keep a shocking transformation secret for so long.

Beckham will play a grumpy knight in King Arthur: Legend of the Sword. While he also appeared in Ritchie's The Man From U.N.C.L.E., he was worried about how fans would react to his acting.

“I am very aware that many sportsmen and other celebrities have turned their hand to acting and failed,” he said. “I know that it is a tough profession, where you need a huge amount of skill and discipline, and I wouldn’t want to push myself forward too soon, without learning more abut it, and doing a lot more practice.” But judging from his new look, he’s very committed to the role.
