"It's Always Sunny in Philadelphia" won't be back for its fourth season until Sept. 18, but FX president John Landgraf is already forecasting a sunny future for the show, saying there'll be 39 episodes beyond that.
In FX terms, that sounds like Seasons 5, 6 and 7.
Landgraf's a big believer in closed-end dramas -- he helped negotiate the seven-seasons-and-out deal for "The Shield," and just announced that "Nip/Tuck" would have a 2011 finale -- but sitcoms, which aren't so serialized, don't necessarily have to play by the same rules.
"Sunny," he said, could go on for as much as "200 episodes, because it's a comedy." It's a popular download on iTunes and as of last week, it's also the most popular show on Hulu, the Web distribution site Fox partly owns.
The executive producers of "Sunny," including creator Rob McElhenney, who's the one who's actually from Philadelphia, are about to start work on a pilot for Fox, "Boldly Going Nowhere," that should keep them busy, considering they also write and star in "Sunny."
