The tour, according to a casting notice, will begin rehearsals Aug. 25 in Manhattan; the production will kick off Sept. 26 in Owensboro, KY. The play is still seeking actors for all the other roles including that of talk-show host Sir David Frost.

Michael Grandage will direct the tour; his associate director is Seth Sklar-Heyn. Producers are Arielle Tepper Madover and the Donmar Warehouse.

According to press notes, "Frost/Nixon tackles the question: How did David Frost, a famous British talk-show host with a playboy reputation, elicit the apology that the rest of the world was waiting to hear from former President Richard Nixon? The fast-paced new play shows the determination, conviction and cunning of two men as they square off in one of the most monumental political interviews of all time."

Langella and Michael Sheen, who had created the roles of, respectively, former President Nixon and talk-show host Frost for London audiences, repeated their work on Broadway. The New York run opened April 22, 2007, and played a limited engagement through Aug. 19, 2007. The cast also featured Remy Auberjonois (John Birt), Shira Gregory (Evonne Goolagong), Corey Johnson (Jack Brennan), Stephen Kunken (Jim Reston), Stephen Rowe (Swifty Lazar/Mike Wallace), Triney Sandoval (Manolo Sanchez), Armand Schultz (Bob Zelnick) and Roxanna Hope (Caroline Cushing).

The Broadway run received Tony Award nominations for Best Play, Best Direction and Best Actor — earning Langella his third Tony win. Langella and Sheen will also star in the film version of Frost/Nixon. Ron Howard's big-screen cast will also include Kevin Bacon, Kate Jennings Grant, Sam Rockwell, Toby Jones and Matthew MacFadyen.

Stacy Keach has appeared on Broadway in Danton's Death, The Country Wife, The Caucasian Chalk Circle, King Lear, Indians (Tony nomination), Deathtrap, Solitary Confinement and The Kentucky Cycle. The actor won a Golden Globe Award for his performance in the TV miniseries "Hemingway," and his numerous screen credits also include "Mike Hammer," "Fat City," "End of the Road" and "Titus."
