We’ve known for some time now that Jeff Daniels would lead a new cable news centric drama pilot at HBO called More as This Story Develops. In addition, Emily Mortimer has been confirmed to take the lead female role with Alison Pill and Olivia Munn taking supporting roles. Now The Wrap reports Law & Order alum Sam Waterston, who played Jack McCoy on the staple legal series until its recent cancellation, has signed on for a role in the promising new series. Waterston will play Charles Skinner, the president of the cable news division which houses news anchor Will McCallister’s (Daniels) own show. This assembly of talent with Greg Mottola (Superbad) at the helm of the pilot has me excited for what looks to be yet another great series on HBO.
