Daniel Radcliffe has been set to make his Broadway musical debut as J. Pierrepont Finch in How to Succeed in Business Without Really Trying, a new version of the Tony and Pulitzer Prize-winning play that will be directed and choreographed by Rob Ashford. The musical bows on Broadway in April, 2011. Broadway Across America partners John Gore, Thomas B. McGrath and Beth Williams will produce with Craig Zadan and Neil Meron. The producers and Ashford are readying an April 25 opening of another Broadway revival, Promises, Promises, with Sean Hayes and Kristin Chenoweth starring. By the time Radcliffe takes the stage, he will have turned 21 and completed Harry Potter and the Deathly Hallows. The final installment of that film franchise will open summer 2011, about two months after opening night. Broadway is in a period when stars are lighting up the stage and providing investors with a measure of confidence. Hugh Jackman and Daniel Craig did a successful run of A Steady Rain, Denzel Washington will soon open a revival of Fences, and Nathan Lane and Bebe Neuwirth are packing houses on The Addams Family (despite awful reviews). Radcliffe creates his own interesting opportunity. He’s got a huge fan base because of the movies, but that young audience could not see his Broadway debut in Equus, not with dark subject matter and the fact that Radcliffe had a nude scene. How to Succeed in Business–which casts him as a young window-cleaner who uses a self-help book and dubious morals to rise from the mail-room to the executive suites of a corporation–is perfectly suitable to a family audience. Radcliffe studied singing and dancing for the last year to prepare for a reading that was held in New York last Christmas week. On hiatus from Potter for the holiday, he flew in, rehearsed and did the reading. Shortly after, he committed to play the Finch role for almost a year.
