Cox will join the previously announced Stacy Keach as the disgraced former President Richard Nixon. Michael Grandage, who directed the original London and Broadway productions, also directs the tour.
Producers of the tour are Arielle Tepper Madover, Independent Presenters Network (IPN), Broadway Across America, Fox Theatricals, Mary Lu Roffe, 101 Productions, LTD and The Donmar Warehouse.
The tour of Frost/Nixon is scheduled to kick off Sept. 30 at the Civic Center in Des Moines, IA.
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."
Designs for Frost/Nixon are by Christopher Oram with lighting by Neil Austin, music and sound by Adam Cork and video design by Jon Driscoll.
The London and Broadway productions co-starred Frank Langella as Nixon and Michael Sheen as David Frost. Langella won a Tony for his performance. Both Langella and Sheen re-create their performances for the upcoming Ron Howard-directed film.
