La Jolla Playhouse extends, again, the run of its ‘Working Girl’ musical

La Jolla Playhouse’s world-premiere musical “Working Girl” has been such a hot ticket with fans that it was extended twice before it even opened in previews last week.

On Tuesday, the Playhouse announced a third extension that will expand the engagement by one week to Dec. 14. Tickets for the additional dates are now on sale.

The Playhouse musical, featuring an original score by Grammy- and Tony Award-winning pop star Cyndi Lauper, is based on Mike Nichols’ 1988 rom-com film of the same name.

The musical tells the story of Tess McGill, a brainy young woman from Staten Island who lands a job as a secretary in the mergers an acquisitions department of a Manhattan brokerage firm. After her opportunistic boss, Katherine Parker, passes off one of Tess’s investing ideas as her own, Tess enlists her fellow secretaries and a handsome Wall Street businessman named Jack, in a risky plan to prove she has what it takes to make it on Wall Street.

Pop/R&B singer and “Moulin-Rouge! The Musical” Broadway alum Joanna “JoJo” Levesque stars in the production as Tess. Tony nominee Leslie Rodriguez Kritzer plays Katharine, TV actor and “American Idol” finalist Anoop Desai stars as Jack, Broadway actress Ashley Blanchet stars as Cyn, Tess’s best friend from Staten Island, and Joey Taranto stars as Tess’s Staten Island boyfriend Mick.

For the musical adaption, which is directed by Playhouse Artistic Director Christopher Ashley, Broadway playwright Theresa Rebeck is adapting Kevin Wade’s 1988 screenplay for the stage.

Lauper has written the ’80s-inspired score and lyrics for the “Working Girl” musical, with the help of a few friends on a couple of songs: Rob Hyman, who she co-wrote the 1983 single “Time After Time” with, Sammy James Jr., who wrote the song “School of Rock” for the film and musical of the same name, and rapper Cheryl James (Salt of the rap duo Salt-N-Pepa) who has contributed some lyrics.
