Eleven years after starring in the #1 movie of all time (I’m still crossing my fingers for The Dark Knight), Titanic‘s Kate Winslet and Leonardo DiCaprio are reuniting for a new movie together.

In Revolutionary Road, the former star-crossed lovers play a seemingly happy couple struggling to conform in the 1950’s.

And while it’s not surprising to hear that the chemistry between Winslet and DiCaprio remains strong, it’s interesting to hear that the intimacy was quite awkward the second time around. For those who don’t know, the Richard Yates adaptation was directed by Sam Mendes, Kate Winslet’s husband.

In an interview with Entertainment Weekly, the Oscar-nominated actress said she had a hard time feeling comfortable with the sex scenes.

“I just kept saying, ‘This is too ... weird.’ And Leo was like, ‘Oh, get over it.’ And I’m going, ‘Yeah, a little reminder: You’re my best friend. He’s my husband. This is a bit weird.’ “

(This coming from the woman who was nude for a good portion of Little Children.)

But it wasn’t like Kate didn’t know what she was getting into. In fact, she was instrumental in making the reunion happen.

“We knew that if we were going to do something again, it had to be something big and emotional. I played this very clever cat-and-mouse game to get my husband and then my best friend involved.”

Will Rose and Jack be able to generate sparks like they did before? Find out when Revolutionary Road opens on December 26. (BTW - that’s the same day Valkyrie is now scheduled to premiere.)
