Rachel Weisz doesn't "respect the rules" in her marriage to Daniel Craig.
The 42-year-old actress - who tied the knot to the James Bond star in June 2011 in New York - admits her marriage to the actor feels different to the long-term relationship she had with her former partner Darren Aronofsky.
Rachel - who has six-year-old son Henry with the Black Swan director - said: "It's different being married than living with your partner. There is a contract.
"You don't necessarily have to think about respecting the rules, but it is just there. It's in your heart, it's not like a piece of paper."
While Weisz said she doesn't play by the rules with Craig, the couple - who first met in 1994 before falling for each other on the set of thriller movie Dream House in 2009 - have agreed to never speak about their acting roles to each other.
In an interview with The Sun, she explained: "I don't talk about my work, and nor does he. It's very private.
"There is nothing worse than two actors getting together and talking about acting. It's like the end - it's the worst."
Weisz's latest film role sees her playing the Wicked Witch of the East in forthcoming fantasy adventure movie Oz: The Great And Powerful - a Wizard Of Oz prequel - and the brunette beauty simply enjoyed playing an evil role.
She added to The Sun: "It's like a playpen - you get to act out stuff that you are not allowed to do in real life.
"But I don't think I got rid of my demons or anything. This film is just not serious, it's fun. My demons are all still there."
