A new Stephen Sondheim musical could receive its premiere as soon as next year. As first reported by The Washington Post, at an event at the Glimmerglass Festival in Cooperstown, New York, Sondheim said that he hopes his new musical (which is based on two Luis Buñuel films and has a book by playwright David Ives) will debut at the Public Theater in the fall of 2017, especially since an opera based on one of the same Buñuel films is going to be produced at the Metropolitan Opera at the same time. Sondheim’s last new musical, “Road Show,” received its premiere at the Public Theater in 2008 following many years of development.

Signature Theatre founder dies

James Houghton, founder of off-Broadway’s Signature Theatre, died on Tuesday at age 57 following a two-year battle with stomach cancer. Under Houghton’s leadership, the Signature Theatre became one of New York’s most pre-eminent off-Broadway institutions, with a distinctive mission of focusing on individual American playwrights and producing multiple works by each playwright over a fixed period of time. In 2012, the company moved to a new multi-theater complex at Pershing Square and its annual programming has more than doubled.

‘Harry Potter’ parody scores off-Broadway transfer

“Harry Potter and the Cursed Child,” which just opened in London to great reviews and a huge box office advance, is likely to hit Broadway soon. But for the time being, you can check out the “Harry Potter” parody “PUFFS or: Seven Increasingly Eventful Years at a Certain School of Magic & Magic,” which will transfer off-Broadway to The Elektra Theater beginning Sept. 29, following a hit run at the Peoples Improv Theater. “PUFFS” is about the unnoticed classmates of Harry Potter who “try to keep their heads down and get a basic wizarding education.”

The goal is for it to open on Broadway in two years. The film, which starred Matt Dillon, is about a young boy who takes a job at a beach resort in the summer of 1963.
