30 Rock - Season 6 - Casting News - Emma Stone, Andy Samberg and Nick Cannon to Guest

How fitting to have a Stone on a Rock: Emma Stone will make a cameo in an upcoming episode of 30 Rock, along with Andy Samberg and Nick Cannon, series creator/star Tina Fey tells EW.

In the Jan. 26 episode of the NBC comedy, Jenna (Jane Krakowski) stars in “a movie from the producers of Valentine’s Day and New Year’s Eve called Martin Luther King Day,” says Fey. “I want to lay claim to that bit before anyone gets it. It’s a movie that has everyone in the world in it.” That includes the aforementioned actors from The Help, Saturday Night Live, and Up All Night, who will be seen in a trailer for the faux film.

30 Rock, which kicks off its sixth season Thursday at 8 p.m., will also feature such guest-stars as James Marsden, Mary Steenburgen, Will Arnett, Denise Richards, Kelsey Grammer, and Kristen Schaal.
