Gone Girl - (2014)

Who could forget the sex scene between Rosamund Pike and Neil Patrick Harris which had a grisly end.

Rosamund plays Amy Dune in the psychological thriller and in one memorable scene Amy ends her ex-boyfriend Desi - played by Neil Patrick Harris - after seducing him.

Neil revealed that he and Rosamund were responsible for choreographing the scene themselves, being allowed to present it to director David Fincher before filming.

He said: “They said, like, 'Go rehearse that and present it to us.

“Rosamund and I just rehearsed how we wanted to have the scene happen.

“We had to go find David Fincher, who was in another room, and he came back in and sat there while we showed him. He was like, ‘Yeah, that will work.’ But that was different times.”
