The hour-long talk show airs late nights on NBC. Harris was scheduled to appear on May 5 but was bumped to the Wednesday night-Thursday morning show as a guest.
Harris, known to television audiences as the title character in the '80s sitcom "Doogie Howser, M.D.," has become quite the stage star in recent years. He appeared in a Los Angeles productions of Rent and Sweeney Todd which led to performing the latter again for Lincoln Center's Sweeney Todd: Live in Concert. Harris made his Broadway debut in the play Proof and followed up that stint with a run as the Emcee in Roundabout's Cabaret.
Assassins began performances March 31 abd opened on Broadway April 22. The musical theatrically retells the stories of the nine individuals who took aim at eight different presidents — the four successful and five attempted assassins. The stageshow filled with song anachronistically weaves together scenes wherein they all interact with one another.
The ensemble cast features Neil Patrick Harris (Proof, Cabaret) in dual roles as The Balladeer — who comments on the action to the audience — and arguably the most infamous assassin, Lee Harvey Oswald. Michael Cerveris (Titanic, Tommy) swaggers as the first successful presidential assassin John Wilkes Booth. James Barbour (Jane Eyre, Carousel) portrays William McKinley killer Leon Czolgosz. Denis O'Hare (Take Me Out) cakewalks as the eccentric office seeker/James Garfield murderer Charles Guiteau. Mario Cantone (The Violet Hour) takes on Samuel Byck who threatened Richard Nixon with a 747. Jeffrey Kuhn (Ragtime) plays FDR gunman Giuseppe Zangara. Alexander Gemignani plays the Jodie Foster-obsessed Ronald Reagan shooter John Hinkley. And Becky Ann Baker (Titanic) and Mary Catherine Garrison (Debbie Does Dallas) play Gerald Ford's femme fatale Sara Jane Moore and Lynette "Squeaky" Fromme, respectively.
A shorn Marc Kudisch (Thoroughly Modern Millie) is also featured in the cast as the Proprietor, who sets the show in motion and provides weapons and more to the assassins. James Clow, Merwin Foard, Eamon Foley, Kendra Kassebaum, Ken Krugman, Anne L. Nathan, Chris Peluso, Brandon Wardell and Sally Wilfert play a variety of roles in the ensemble.
