FXX is investing in the future of Rob McElhenney, Charlie Day and Glenn Howerton. The younger-skewing FX offshoot has inked a new three-year overall production deal with the It's Always Sunny in Philadelphia trio that includes a two-season renewal for the comedy as well as a straight-to-series pickup for a new comedy starring Tracy Morgan, The Hollywood Reporter said.

Included in the deal is a yet-to-be announced comedy pilot order and three script pickups. (The new deal for their RCG Productions banner comes after FX first inked the trio to a three-year overall pact in 2011.)

The renewal for It's Always Sunny -- picked up for two seasons of 10 episodes each -- will take the series through its 12th season. The series will become the longest-running live-action comedy in cable history, and its 12 seasons will tie My Three Sons for the second-longest-running live action comedy in TV history.

The Morgan series, meanwhile, is for an entirely different project than Death Pact, the comedy pilot the 30 Rock alum was set to star in. That project, known internally as Do or Die, is now dead. The new untitled half-hour series was created by McElhenney, Day, Howerton and Luvh Rakhe. RCG will executive produce and serve as showrunners alongside Rakhe. Eric Tannenbaum, Kim Tannenbaum and Nick Frenkel will executive produce. The untitled project will be paired with the upcoming 10th season of It's Always Sunny and launch in January.

In addition to the series order and two-season renewal, FX and FX Productions have also put into development a comedy pilot yet to be announced as well as three scripts from RCG.

It's Always Sunny -- created by McElhenney and exec produced by McElhenney, Day, Howerton, Michael Rotenberg, Nick Frenkel and Tom Lofaro, is one of ad-supported cable's highest-rated comedy series among adults 18-49, 18-34 and men 18-34. It's the first basic cable comedy to air in syndication on another network (Comedy Central).
