Sullivan, according to Variety, fell through a trap door on the stage of the Public's Delacorte Theatre. The director was treated for four fractured ribs and a collapsed lung at a nearby hospital.
The industry paper says Sullivan is expected to recovery quickly from his various injuries, although when he would return to the production is still unclear. There has been no announcement whether Midsummer's previews will be delayed.
The Shakespearean production, which co-stars Tim Blake Nelson, Martha Plimpton, Keith David and Mireille Enos, is currently scheduled to begin previews Aug. 7 with an official opening Aug. 23.
Sullivan — one of New York's most prolific directors — was represented on Broadway last season with the revival of Craig Lucas' Prelude to a Kiss. This season he will direct the Broadway revival of The Homecoming, which will co-star Ian McShane, Raul Esparza and Michael McKean.
A favored director of such playwrights as Donald Margulies and the late Wendy Wasserstein, Sullivan has been nominated for six Tony Awards for Direction of a Play, and won for David Auburn's Proof in 2001. His other Broadway credits include Rabbit Hole, Julius Caesar (with Denzel Washignton), Brooklyn Boy, Sight Unseen, The Retreat From Moscow, Morning’s at Seven, Major Barbara, A Moon for the Misbegotten, Ah, Wilderness!, An American Daughter, The Sisters Rosensweig, Conversations With My Father, The Heidi Chronicles and I’m Not Rappaport. His recent Off-Broadway projects include Stuff Happens, Third, Intimate Apparel, Ten Unknowns and Dinner With Friends.
Sullivan is known for his development of new plays. From 1984-1997 he was the artistic director of the Seattle Repertory Theater, where he directed more than 60 productions.
