“There could be a sequel at some point if everyone is game to get the gang back together,” she told the New York Daily News.
“It could be really fun a few years from now to pick it up and see what those crazy Dunnes are up to a few years down the road and if they got on – not well I don’t think.

Were Gone Girl to return to the silver screen, Flynn would want the same actors to reprise their roles.
“I would have to have the exact same people to do it – I would want Rosamund, Ben and Fincher to do it,” she said.
Flynn is currently working with Fincher on the HBO remake of Channel 4 conspiracy thriller Utopia as well as producing a TV show based on her novel Sharp Objects and writing a comic book called Masks.
Not much time for Gone Girl 2 just yet, then.
