There won’t be any let-up for Charlie Sheen’s Anger Management issues any time soon.

Appearing at the Television Critics Association’s winter press tour in Pasadena on Wednesday, FX president John Landgraf detailed that the comedy — which after a 10-episode freshman run was renewed for 90 episodes (!) — will unspool that massive inventory virtually non-stop for the next two years starting Thursday, Jan. 17.

“We’ll essentially have 45 new episodes per year,” he said, nothing that the only breaks will be for holiday and sports programming and such.

As for any tweaks made for Season Mega-2, Landgraf said that, as previously announced, Sheen’s real-life father Martin Sheen was made a series regular, as the fictional Charlie’s own dad. “I thought it would be a better series if it was also a multi-generational series,” he explained.

Other topics tackled by Landgraf:

* “There’ll definitely be one more year” of It’s Always Sunny in Philadelphia, which already had been renewed through Season 9, “probably two.”

* Landgraf had no new casting news for American Horror Story Season 3, outside of the previously reported Jessica Lange. “That is such an auteur work on Ryan [Murphy]’s part,” he noted. “He tells me what he’s going to do and I say, ‘Great!'”

* Asked to weigh in on cable rival AMC’s proclivity to replace showrunners — most recently for The Walking Dead Season 4 — he acknowledged, “AMC managed to make a successful transition” during the zombie drama’s Season 2, but “it remains to be seen if they can pull that feat off again.” Hailing FX’s near-perfect track record in that regard, he shared, “You’re going to have bad moments, fights and arguments…. That said, we’ve never fired a showrunner… so we’re batting 1.000.” Explaining his network’s philosophy, he added, “These shows are very personal, you can’t ‘plug-and-play.’ The author needs to complete the journey…. What would [The Shield] have been if Shawn Ryan hadn’t been around for the last season?”
