Daniel Radcliffe will star in "How to Succeed in Business Without Really Trying" early next year.
The 20-year-old British actor, who won rave reviews for his Broadway debut in the play "Equus" in 2008, will take up the role of J. Pierrepont Finch in the musical based on Shepherd Mead's satirical self-help book of the same name.
The musical follows Finch, a young window-cleaner who follows the advice of the self-help book and rises from the mail room to vice president of advertising at a company.
"Finch's unorthodox and morally questionable business practices jeopardize not only his career but also his romance with secretary Rosemary Pilkington," producers said in a statement.
The Tony and Pulitzer Prize-winning musical was first performed on Broadway in 1961.
Radcliffe is currently filming the eighth and final film in the "Harry Potter" series based on the seven books by author J.K. Rowling.
