Laura Benanti, Andrew McCarthy and John Lavelle will head the cast of the one-night-only event, which comprises three one-acts set at New York's Plaza Hotel: "Visitor From Mamaroneck," "Visitor From Hollywood" and "Visitor From Forest Hills." The Benanti-McCarthy pairing casts the two as former high school sweethearts who reunite one night at the Plaza. Jonathan Ross will direct the reading, which is being produced by Suzy Myers and Jamie McGonnigal. (Casting for the other two one-acts will be announced shortly.)

The evening will benefit Opening Act, which "provides free after-school theatre programming to New York City's most underserved public high schools."

Plaza Suite opened on Broadway at the Plymouth Theatre in Feb. 14, 1968, playing 1,097 performances before closing Oct. 3, 1970. The original cast — directed by Mike Nichols — included George C. Scott, Maureen Stapleton, Bob Balaban, Claudette Nevins and Jose Ocasio.
