"Gone Girl" movie cast Neil Patrick Harris' wedding to David Burtka in Italy last week was an intimate ceremony attended by family and close friends. Their twins, Harper and Gideon, were also part of the entourage.

According to E! News, "Gone Girl" movie cast Neil Patrick Harris, 41, finally exchanged vows with David Burtka, who is two years his junior.

"We just have been together over 10 years. I think when our kids got to the age where they were having reasonable conversations-where they're asking lots of why questions-then it seemed like to be able to have a real clear-cut explanation of who their daddy is. I think its great [to say], 'He's my husband."

The actor also dished out details of the "Gone Girl" movie cat Neil Patrick Harris' wedding to The View, which counted Elton John as one of the VIP guests.

"It was nice. It was very small, intimate. Only 45 people were there. We did a destination wedding so it kind of kept the numbers down. I just wanted to be able to say nice things about David, to David, in front of the people who matter most to us...a declaration to share in front of our kids," he told The View, per E! News.

"When you watch other people say their vows and they get all choked up you think, 'C'mon, pull it together, man!' Then when you're standing there and it's you and you have this piece of paper that's shaking...you can't help but just get super-duper choked up. I wasn't a crying mess or anything, but they're important words that need to be heard by the person that you're [marrying]...it was fun," he added about"Gone Girl" movie cast Neil Patrick Harris' wedding.

In "Gone Girl," Neil Patrick Harris plays Desi Collings, the former boyfriend of Amy Dunne (Rosamund Pike) and the prime suspect in Nick's (Ben Affleck) mind.

In fact, the New York Post called the attention of viewers on the performance of Neil Patrick Harris, who is more known for his comedic chops than in drama.

"It was already one of the year's most anticipated movies, but now 'Gone Girl' has gone and upped the ante with a special ingredient: a sunken-eyed Neil Patrick Harris," it said.
