Mark-Paul Gosselaar, Justin Kirk join ‘Understudy’

NEW YORK — Mark-Paul Gosselaar (GAHS’-uh-lur) and Justin Kirk will join the already announced Julie White in “The Understudy,” a comedy about one of the most underappreciated jobs in theater.

Artistic director Todd Haimes says the Roundabout Theatre Company production will open Nov. 5 at off-Broadway’s Laura Pels Theatre. Previews begin Oct. 9.

Gosselaar is best known for playing Zack Morris on television’s “Saved By the Bell,” while Kirk currently appears on the Showtime comedy “Weeds.”
