Melanie Griffith, Amanda Seyfried to star onstage

Want to watch an A-lister scramble? A whole bunch — including Melanie Griffith, Amanda Seyfried, Peter Dinklage and Pablo Schreiber — will be doing exactly that on a Broadway stage.

They’re appearing on Monday in the 14th annual benefit “The 24 Hour Plays on Broadway,” which asks more than a dozen actors and several writers and directors to come up with original short plays over the course of a day. Proceeds help the Urban Arts Partnership.
