Rosamund Pike dished about her upcoming sex scene with Neil Patrick Harris in the upcoming thriller "Gone Girl," which hits theaters Oct. 3.
The actress, 35, told Seth Meyers that preparing for the scene was "a very odd experience," noting that director David Fincher asked her and Harris to "rehearse this scene for two hours, alone, on an empty soundstage -- just Neil and myself."
"That is when it feels highly inappropriate," she added. "You're alone with a man who's not your husband who also has a husband ... he's in his underwear, you're in your underwear and you're sort of dry humping on a bed."
Harris, 41, tied the knot with husband David Burtka in Italy last month. He said the ceremony, which took place at a rented castle, was "less about a proclamation and more about a declaration that I was able to share in front of our kids, and that he could do back for me."
