Hair and Hamlet are coming to Central Park this summer. The Public Theater’s free Shakespeare in the Park program will begin May 29 with Hamlet , starring Michael Stuhlbarg (of The Pillowman), according to Variety. It will be the first Hamlet since 1975, when Sam Waterston had the title role. Hair was presented at Central Park’s Delacorte Theater last September in a two-night concert version commemorating the musical’s 40th anniversary. All 27 cast members from the concert have been invited to return, but so far only Jonathan Groff (of Spring Awakening) and Will Swenson (110 in the Shade) have been confirmed. For the full production this summer, Diane Paulus (“The Donkey Show”) returns to direct. The Hair appointment has been made for July 22 through Aug. 17.
