What do you do in your spare time? Movie actor Jesse Eisenberg writes plays, and one of those plays will be part of the Rattlestick Playwrights Theater’s 2011–2012 season. It’s called Asuncion; it opens October 12 at the Cherry Lane Theatre in New York; and it’s about two roommates — Edgar, an anti-American-imperialism blogger, and Vinny, a Black Studies Ph.D. student — who begin living with a Filipina woman named Asuncion. Eisenberg will play the blogger, which is definitely the best sentence we’ve written all day.
