Glenn Howerton is gearing up for Season 9 of "It's Always Sunny In Philadelphia," which is premiering Sept. 4. But that doesn't mean the writer/director/actor doesn't have a few other irons in the fire.
Check out our video interview above with the man we call "Dennis"; below are five things you should know from our chat with Howerton at Comic-Con this July.
1. Aaron Paul will not be guesting in Season 9 of "Sunny."
"The Breaking Bad" actor has declared his love for the FX show on many occasions, but Howerton said that the prospective casting just didn't work out. However, he warns that guests this season like the "very funny" Josh Groban, Seann William Scott (as Mac's cousin) and "Rowdy" Roddy Piper are all on tap.
2. No one at FX or other networks or shows have even asked to have a crossover concept episode with "Sunny."
"It wouldn't be complete out of the question, but it is kind of our own universe," Howerton explained of the Philadelphia from the show. Though, he conceded that a "Scooby Doo" adventure might be fun. Too bad "Breaking Bad" ends after this season...
3. The "unexpected" element from the first episode of the new season of "It's Always Sunny in Philadelphia" reveals something new about Mac.
Viewers might experience Howerton's character actually "genuinely care about something." Besides himself? Weird!
4. Gail the Snail, Rickety Cricket, the McPoyles and Wang are returning to Season 9.
Charlie and Frank's landlord is back for the first time since Season 1, and there's always a guarantee of former elementary school heeby-jeebies from Jimmi Simpson and Nate Mooney.
5. Howerton hopes to keep up with dramas as much as he does comedy.
While he recently released CollegeHumor's new film "Coffee Town" to iTunes, Howerton thinks its important to do projects aside from "It's Always Sunny in Philadelphia."
"I would never want to resent ["Sunny"] because it prevents me from doing other things," he said. The next thing on his slate: He's producing indie drama "The Wilderness of James" with hopes to release it sometime in the coming year.
