Tina Fey will be complemented by another star-studded group of cameos in the upcoming season of 30 Rock, including The Help’s Emma Stone, SNL’s Andy Samberg, and Up All Night’s Nick Cannon.
Fey, creator and star of the comedy, revealed to EW that the preceding actors will appear in cameo roles "in a movie from the producers of Valentine’s Day and New Year’s Eve called Martin Luther King Day."
"I want to lay claim to that bit before anyone gets it," Fey quipped. "It's a movie that has everyone in the world in it."
The sixth season of 30 Rock, which will premiere Thursday at 8 p.m., will also feature guest-stars James Marsden, Mary Steenburgen, Will Arnett, Denise Richards, Kelsey Grammer, and Kristen Schaal.
Arnett and Grammer have both previously made cameos on the show.
