New Year's Eve and Valentine's Day are the Hallmark of Hollywood productions—rom coms centered around holidays in which ensemble casts play out their microscopic plotlines which somehow generate lots and lots of manufactured feelings. They're totally manipulative! And lucrative. And now they've got some competition from the folks at 30 Rock, where on the show Jenna Maroney is starring in Martin Luther King Day. Check out the trailer, where you'll also spot: Nick Cannon, Emma Stone, Andy Samberg, Liam Neeson, Kristen Bell, R2D2, John Krasinski, Hugh Grant, and so many more. What, no Ashton Kutcher?
