Audiences are in for a night of romance and 1950s nostalgia when they treat themselves to the delicious drama of Picnic. Maggie Grace and Sebastian Stan crank up the sexual tension on Broadway in the hot revival of William Inge's play, which also stars Ellen Burstyn, Mare Winningham, Reed Birney, Elizabeth Marvel, Madeleine Martin and Ben Rappaport. As the cast celebrated opening night, Broadway.com was there to catch all the pre- and post-show revelry, including plenty of famous faces who stopped by to lend their support (including Stan’s girlfriend Jennifer Morrison and Gossip Girl co-star Chace Crawford).
