David Fincher's upcoming movie Gone Girl has debuted its first trailer.
The highly-anticipated big-screen adaptation of Gillian Flynn's best-selling novel stars Ben Affleck and Rosamund Pike as Nick and Amy Dunne, a married couple whose marriage is rocked when Amy disappears without a trace on their fifth wedding anniversary.
Flynn has written the script for the movie, which will deviate from the book version, featuring a reworked ending.
The author said of the revised third act: "Ben was so shocked by it. He would say, 'This is a whole new third act! She literally threw that third act out and started from scratch'.
"There was something thrilling about taking this piece of work that I'd spent about two years painstakingly putting together with all its 8,000,000 LEGO pieces and take a hammer to it and bash it apart and reassemble it into a movie."
The teaser trailer features a cover of Charles Aznavour's She from Psychedlic Furs frontman Richard Butler.
Gone Girl will be released in cinemas on October 3.
