This Sunday, August 19, is your last opportunity to see three star vehicles on Broadway. The first is Deuce, a play about two former tennis players played by Angela Lansbury and Marian Seldes. The second is Peter Morgan's Frost/Nixon, starring Frank Langella and Michael Sheen as former U.S. President Richard Nixon and British journalist David Frost, respectively. And the last is Old Acquaintance, a Broadway revival featuring the marvelous Harriet Harris and Margaret Colin.
