The 2014 gala, entitled In Here, Life Is Beautiful, will begin at 7 PM with dinner and a live auction, followed by a tribute to Mendes.

Mendes' association with Roundabout began in 1998 by directing the Tony Award-winning Cabaret, which will return to Studio 54 (again under the direction of Mendes and Rob Marshall) March 21 with Alan Cumming and Michelle Williams.

The tribute will feature performances by Ethan Hawke, Bernadette Peters, Marc Shaiman, Alan Cumming, Brian d'Arcy James and Aaron Krohn. Appearances will also be made by Helen Mirren, Jeremy Irons, Maggie Gyllenhaal, Cynthia Nixon, Kathy Bates, Dylan Baker and Richard Easton, among others.
