It will begin performances at the Apollo Theatre Sept. 18 for a run through Oct. 6.

Rees, who won the 1982 Tony Award for Best Actor in a Play for playing the title role in the RSC's production of The Life and Adventures of Nicholas Nickleby, is currently represented on Broadway by his Tony nominated co-direction of Peter and the Starcatcher. His other Broadway credits as an actor includeThe Addams Family, Uncle Vanya, The Rehearsal, Indiscretions and the brief run of The Red Shoes. He was last seen in the West End opposite Ian McKellen in Waiting for Godot in 2010. He is known for his television work in "Cheers," "The West Wing" and "Grey's Anatomy" as well as for screen roles in "Robin Hood: Men in Tights," "Frida" and "The Prestige." He is an associate artist of the Royal Shakespeare Company, former associate artistic director of the Bristol Old Vic Theatre and former artistic director of the Williamstown Theatre Festival.

In What You Will, Rees provides what press materials describe as a "90-minute gallop through all things Shakespearean" that shows everything "to be or not to be" about William Shakespeare: the greatest soliloquies ever written along with accounts of the funniest disasters ever perpetrated on the stage.  Juliet's foolish nurse, gory Macbeth, Hamlet, Richard II, even Charles Dickens, James Thurber, Noel Coward and Stevie Wonder all make appearances during the evening.
