Rosamund Pike has said she is very proud to be part of the film adaptation of Gone Girl because the book has so many fans.
The Jack Reacher actress took on the role of lead character Amy Dunne, opposite Ben Affleck who plays her husband, for the big screen version of the thriller by Gillian Flynn.
She said: "The anticipation for the film is wonderful, it's really exciting. I went past a new poster for a new novel today and again it's comparing it to Gone Girl.
"It's become the benchmark to compare psychological thrillers to. I'm excited to be part of a film where the appetite is so great."
The plot follows the diaries of a husband and wife after the wife (Rosamund's character) mysteriously goes missing and those left behind try to piece together what happened to her.
Rosamund stars alongside Simon Pegg in the comedy Hector And The Search For Happiness, which is in cinemas now.
