FX president John Landgraf says he expects at least one more season of "It's Always Sunny in Philadelphia," and possibly two.

Landgraf talked about plans for the hit comedy during a panel at the Television Critics Association winter press tour. He also said FX has not "yet" ordered the drama "The Bridge," which would star Diane Kruger and Demian Bichir as cops from both sides of the U.S.-Mexican border.

Asked about AMC's history of problems with showrunners — "Walking Dead" head Glen Mazzarra recently parted ways with the hit show — he also said FX was "batting .1000" in holding onto showrunners.

Only the showrunner of FX's "Wilfred" had left the position, he said — and he remained an executive producer of the comedy.

Landgraf also talked about the creative freedom he is known for allowing his showrunners. He joked that his oversight of "American Horror Story" consists of listening to co-creator Ryan Murphy's ideas and saying "great."

Landgraf said "Sunny" was one of the key shows he credits for FX's success. He brought the show to the network in a deal that gave its producers little pay up front. But they were allowed vast creative freedom, and have become very rich as the show persevered.

The trio behind "Sunny" — Rob McElhenney, Charlie Day and Glenn Howerton — split just $1 million to act, write, produce and star in its seven-episode first season in 2005. McElhenney, the show's creator, kept his job as a waiter.

But under their current deal, they'll divide $40 million total for the show's eighth, ninth and tenth seasons.
