According to a Los Angeles Times report, an unfinished script was the root of the problem. A source close to the production tells EW that Sony agreed to give director Barry Sonnenfeld more time to prep the last act of the film after viewing a promising cut of the first act, which was completed before the holidays. Jeff Nathanson (Catch Me if You Can) had come aboard to work on the script for four weeks, but Etan Cohen (Tropic Thunder), who authored a previous draft, is now back writing. The delays won’t impact the availability of the cast (Will Smith, Tommy Lee Jones, Josh Brolin), says the source, and the film is still locked into its Memorial Day 2012 release date.
