Danny DeVito, Glenn Howerton, Rob McElhenney, Kaitlin Olson and Charlie Day made an appearance at a Sunday panel for their FX comedy wearing outlandish ensembles from "The Nightman Cometh," their infamous musical-within-the-show they toured with in 2009.
The crowd at the pop-culture convention roared when the gang stepped onto the stage.
Before the panel at the San Diego Convention Center, the audience previewed the seventh season premiere, which is set to debut Sept. 15.
While answering questions from fans, the cast teased that the gang will participate in a high school reunion and a child pageant in the upcoming season.
Also Sunday, "Glee" co-creator and executive producer Brad Falchuk told thousands of so-called "Gleeks" gathered at Comic-Con on Sunday that Lea Michele, Chris Colfer and Cory Monteith will appear in future seasons of the hit show.
Reports surfaced last month that the three stars would not return for season four of the musical Fox series. Their characters are high school seniors who are set to graduate at the end of the season three.
"They're seniors, they're graduating, but just because they're graduating doesn't mean they're leaving the show," Falchuk told fans, noting that the actors remain under contract.
