Moore is making her Broadway debut as a Yale University politics professor in the world premiere of David Hare's play, which began previews Nov. 9 and opened Nov. 30 at the Music Box Theatre.

Sam Mendes directs the play, which also marks the Broadway debut of the British actor Bill Nighy. Scott Rudin, Robert Fox, Neal Street Productions, Roger Berlind, Debra Black and The Shubert Organization produce the play, which is a 20-week limited engagement.

In The Vertical Hour, Moore's character and her boyfriend visit the boyfriend's father (Nighy) in the Welsh countryside, where the trio gets into heated discussions about love, death, marriage, parenthood and the Iraq war.

Joining Moore and Nighy in the cast are Andrew Scott, Dan Bittner and Rutina Wesley.

Moore has earned four Academy Award nominations for her work in "The Hours" (a Hare screenplay), "Boogie Nights," "Far From Heaven" and "The End of the Affair." Other film work includes "The Shipping News," "Evolution," "Hannibal," "An Ideal Husband," "Magnolia," "The Big Lebowski" and the forthcoming "Children of Men" and "Savage Grace." Her stage credits include Vanya on 42nd Street Off-Broadway as well as Surviving Picasso, Serious Money and Ice Cream With Hot Fudge. The Music Box Theatre is located at 239 West 45th Street.
