The original script, written by Josh Goldin and Rachel Abramowitz, has also been extensively rewritten, according to Deadline.
The pilot, which follows a group of people involved in organised crime in Nashville, was originally directed by Michael Dinner.
However, the reshoots will be handled by Adam Arkin, due to Dinner's commitment to another FX pilot, Powers.
The majority of the original cast, including Mary Steenburgen, Luke Grimes, Haley Bennett and John Hawkes, are expected to return for the new Outlaw Country pilot. However, some minor roles are expected to be recast.
FX originally picked up Outlaw Country last April and filmed the first pilot episode in late 2010.
