Rosamund Pike is the favourite to take the lead role in the film adaptation of Gone Girl, according to reports.
Reese Witherspoon is producing the film but will not be appearing in it.
If Rosamund is signed she would play Ben Affleck's on-screen wife, who goes missing under mysterious circumstances on the morning of their fifth wedding anniversary.
The first half of the book is mainly diary entries and the script is being adapted by the novel's author Gillian Flynn, with director David Fincher.
Rosamund is currently signed up to a number of other projects including comedy What We Did On Our Holiday with David Tennant and Hector And The Search for Happiness with Simon Pegg.
