How to Succeed in Business Without Really Trying? It’s easy. Simply cast Daniel Radcliffe in the lead of a popular vintage Broadway musical, and sit back and watch his multitude of young Harry Potter fans throw money at the box-office.

Fortunately, the people responsible for the 50th anniversary revival of this classic show with its indelible score by Frank Loesser have tried. While this production directed and choreographed by Rob Ashford rarely hits the musical comedy heights that it should, it’s a solidly entertaining rendition that should well please audiences.

The immediate question, of course, is whether Radcliffe is up to the demands of his leading musical comedy role. The answer is a qualified yes. The young actor has clearly worked hard, very hard, and while his singing is merely pleasant at best, he displays a very likeable and charming stage presence as J. Pierrepont Finch, the relentlessly ambitious schemer working his way up the corporate ladder. He lacks the inspired comic impishness of such predecessors as Robert Morse and Matthew Broderick—his too earnest delivery of the classic self-love number “I Believe in You” falls flat, for instance—but his youthful eagerness serves him well here. He speaks and sings with a flawless American accent, and his athletic dancing reveals plenty of hours spent in the rehearsal room.

Ashford’s staging, very reminiscent of his work in the recent revival of that other corporate-themed, 60’s set musical, Promises, Promises, is suitably fast-paced and energetic. But it only truly soars with the fabulous choreography in the 11 o’clock number “Brotherhood of Man,” which stops the show.

The production’s other valuable asset is John Larroquette, terrific as the clueless company head J.B. Biggley. His comic interactions with Radcliffe are frequently inspired, particularly in their duet on the elaborate production number “Grand Old Ivy.”

Other than Rob Bartlett, who scores big laughs in his dual roles as the veteran mailroom head and CEO Wally Womper, and Ellen Harvey, drolly funny as Biggley’s savvy secretary, the supporting players are merely adequate. Rose Hemingway is appealing but fairly bland as the ingénue, Rosemary; Tammy Blanchard hits only predictable notes as the tarty Hedy La Rue; and Christopher J. Hanke fails to exploit the rich comic potential of his role as Finch’s rival, Bud Frump.

But the show itself, with its hilariously funny book by Abe Burrows, Jack Weinstock and Willie Gilbert, still holds up marvelously well, and is if anything even more relevant in today’s cutthroat corporate world. And, in a cannily hip gesture, the voice of the narrator is provided by current journalism glamour boy, Anderson Cooper.
