The show creators are actually finding it difficult to take a final call, as two great actresses vying for the. While there are rumors that Rachel McAdams may eventually get the role, show creator Nic Pizzolatto has remained silent on the issue.

While the inclusion of Farrell and Vaughn was confirmed in October, Taylor Kitsch signed a deal only recently for a lead role in the series.
