He won't be Harry Potter boy wonder for much longer. Actor Daniel Radcliffe is set to head the cast of Broadway musical How to Succeed in Business Without Really Trying. A reading for the play is scheduled for December, as producers test out the piece for a possible Rialto revival. How to Succeed is essentially a lighter, musical version of Mad Men, and chronicles the rise of a window cleaner who follows a self-help manual to rise to the top of the World Wide Wickets Co. The musical was revived in 1995, with Matthew Broderick heading the cast and earning a Tony for his role. It may feel a little soon to mount another revival, but with corporate America in upheaval, the chance to mock the business world may be too good to pass up.
