We still don't know exactly why Megan Mullally quit the Broadway revival of "Lips Together, Teeth Apart," which was supposed to provide Patton Oswalt with his debut on the Great White Way over the weekend — but we do know that Oswalt has reason to stick around New York City this month and something to fill his free time.

The trades reported tonight that Patton Oswalt picked up a co-starring role in Beach Lane, the NBC half-hour sitcom pilot featuring Matthew Broderick as "a celebrity author hired by an irresponsible millionaire heir to run his struggling small-town newspaper in the Hamptons." Oswalt will play the irresponsible millionaire heir. Kristen Johnston also co-stars, in the sitcom created by Paul Simms and produced by Lorne Michaels and Marci Klein.

The Beach Lane pilot will tape before a sold-out audience April 22 in New York City. (THR, Audiences Unlimited)
