The 31-year-old actor - who has a four-year-old son with ex-wife Evan Rachel Wood - tied the knot with his 'Fantastic Four' co-star in July after two years of dating, and while they are having a "great time" together, he insists nothing has changed in their relationship.

He told 'Entertainment Tonight': "We're having a great time. For me, nothing feels any different, and I think that's the way it should be. You make a dedication to each other, and that's it.

"But I can't believe it's still so early [into our marriage]. It feels like we've been married forever."

The 'Jumper' actor and his 34-year-old wife love low-key date nights together.

He explained to E! News: "Netflix and chill is date night. Couch. Postmates. That's the date night. Our perfect date night is a movie and dinner."

However, the British actor still feels very proud when he and the former 'House of Cards' star walk the red carpet together.

He gushed: "I'm very fortunate to stand next to her."

Meanwhile, Jamie is currently sporting bandaged fingers after injuring his hand working on his new movie 'Donnybrook', and though playing a bare-knuckle fighter is a huge departure for him, he's enjoying the role.

He said of his injuries: "I'm shooting a film right now about this guy who enters a bare-knuckle fist fight tournament to win money to try and save his family, so I was hitting a bag.

"I just started shooting the movie.

"I'm literally the least violent, aggressive person one would ever imagine, so the idea of me playing this role is kind of ridiculous. But it's fun so far."
