Had things turned out differently, it wouldn't be "Gone Girl" hitting theaters in a couple of weeks. For a moment, it looked like David Fincher would be going blockbuster, directing Disney's "20,000 Leagues Under The Sea." Fincher had done location scouting in Australia in 2012, and in the spring of 2013, the government had gone ahead and approved tax rebates and refunds for the production. However, one holdup remained: casting. Fincher had sought his "Fight Club" and "Se7en" star Brad Pitt, but he passed on the movie, while the director also had his eye on Channing Tatum. But it seems the filmmaker and studio could never get on the same page about who should star.
