Kate Winslet felt awkward filming a sex scene with Leonardo DiCaprio

She says, "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.' "I hadn't realized how much my chemistry with him since Titanic would still stick. It's great to discover we can just slip right into it, like muscle memory." And Winslet confesses that she knew she would work with DiCaprio again, and orchestrated getting him on-board the movie. She adds, "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."
