The Hunger Games: Catching Fire star tied the knot with his actress love in a romantic ceremony attended by family and friends.
A leaked Instagram photo of the nuptials showed the Inbetweeners film actress in a beautiful tulle and lace gown and her groom looking dapper in a suit.
The snap captured the happy moment at which the new husband and wife cut into their show-stopping wedding cake.
Sam, who stars alongside Jennifer Lawrence in the hit franchise, made no secret of falling head over heels in love with Laura, who has described as his "female counterpart".
"It's the sickliest story ever. I walked into an audition room, I saw her and I knew," the 27-year-old said of his new wife. "I'm not kidding for the life of me.
"She was reading in for a part and it's my fourth recall. I've done three auditions with this other girl reading and this girl walked in and I walked out of the audition, couldn't care less if I got the part."
"I called my agent, I said, 'Mate, I am in love.' He's like, 'How did the audition go, mate?' I was like, 'No, no, you don't understand. I have just met the woman I want to marry."

"Then, that evening I went to a party in East London and at 5am, I stayed up all night having fun with my friends, got on the first tube or the subway home, the subway doors opened at my stop, she was standing there. I’m not kidding. This actually happened.
"She was like, "Sam!" and I was like, 'Oh my god, I'm still on the same clothes. My god, I smell.' But yeah we exchanged information."
The British actor also revealed that the new Mrs Claflin, 27, reminds him of his mother.
"I think I found the one that I want to live with the rest of my life, luckily," he said. "She's my female counterpart is the best way to describe her.
"'She reminds me of my mum so much which I think—a guy will know, right? It's important. Your mum knows like everything.
"She has a lot of very similarities but at the same time she's very different and the elements that she's different from my mom, she's me.
'My mum being the first woman I ever loved obviously and is now the second woman I've ever loved probably is you know, yeah."
