On the Twentieth Century will begin previews Feb. 12, 2015, towards a March 12 opening night. It is scheduled to play a limited 20-week engagement through July 5 at the American Airlines Theatre.

Roundabout associate artistic director Scott Ellis (a six-time Tony Award nominee for She Loves Me, Steel Pier, 1776, Twelve Angry Men, Curtains, The Mystery of Edwin Drood) will direct On the Twentieth Century with choreography by Warren Carlyle, a Tony Award winner for After Midnight.

Chenoweth, a Tony Award winner for You're a Good Man, Charlie Brown and a Tony nominee for Wicked, plays Lily Garland opposite film, television and Broadway star Gallagher ("The O.C," "American Beauty," Guys and Dolls, The Country Girl) as Oscar Jaffe.

Joining them are Karl (Rocky) as Bruce Granit, Mark Linn‐Baker (You Can't Take It With You) as Oliver Webb, Michael McGrath (Nice Work If You Can Get It) as Owen O'Malley and Wilson (Grey Gardens) as Letitia Primrose.

The full cast will be announced shortly. The musical — featuring music by Cy Coleman and book and lyrics by Betty Comden and Adolph Green — premiered on Broadway in 1978 under the direction of Harold Prince and won Tony Awards for Best Original Score and Best Book of a Musical.

The full cast will be announced at a later date.

Here's how Roundabout bills the classic: "It's nonstop laughs aboard the Twentieth Century, a luxury coach travelling from Chicago to New York City. Luck, love and mischief collide when the bankrupt theater producer Oscar Jaffe (Gallagher) embarks on a madcap mission to cajole glamorous Hollywood starlet Lily Garland (Chenoweth) into playing the lead in his new, non-existent epic drama. But is the train ride long enough to reignite the spark between these former lovers, create a play from scratch, and find the money to get it all the way to Broadway?"

The design team includes David Rockwell (sets), William Ivey Long (costumes), Donald Holder (lights), Jon Weston (sound), Kevin Stites (musical director), Larry Hochman (orchestrations) and David Krane (dance arrangements and incidental music).
