As NBC is pinning its hopes for a Thursday ratings turnaround on The Blacklist, which is getting ready to move to the competitive night, the "Leverage" And "The Librarian" Wrap Partynetwork is betting on another conspiracy thriller from the producers of its flagship drama, Sony Pictures and Davis Entertainment. But did NBC make a last-minute change on the project’s lead character?

The network has given a pilot order to drama Endgame, written by Leverage co-creator John Rogers, creator of TNT’s breakout new drama The Librarians. The project, which already had a pilot production commitment, is described as a high-octane thriller set in the high stakes world of Las Vegas. It centers on a former sniper turned security expert who is drawn into a mysterious conspiracy that forces him to complete a series of heroic challenges in order to save innocent lives. Rogers executive produces with Davis Entertainment’s John Davis and John Fox.

There appears to be a new twist in the logline for Endgame. In the original description of the project when it was sold to NBC in September, the lead was a former intelligence officer. That was a background the character had throughout the development process until he was listed today by NBC as a former sniper. This year, NBC already tweaked the lead characters on another drama project, Love Is A Four Letter Word, just before the pilot order, making the central couple black, likely influenced by one pop culture phenomenon, Fox’s breakout hit Empire. Now the network may have done the same on Endgame in light of the blockbuster success of the feature American Sniper. I hear the creative auspices of the project were unaware of the change and that the tweak will likely be dropped, with the character keeping his original intelligence officer background.

This marks the second Sony-produced drama with a pilot production commitment to get a pilot order at NBC, joining Game Of Silence, from Carol Mendelsohn and David Hudgins.

It should be a good couple of weeks for Rogers, whose TNT drama series The Librarians, based on the network’s hit Librarian movie franchise, is expected to get a second season renewal shortly.
