Broadway had a healthy year at the box office this season. But more and more it seems, theatre is looking for its inspiration from the movies. “Despite these flashes of risk-taking creativity, the looming presence on Broadway this season has been the movie-musical and the musical revival. In the former genre, the year’s biggest smoking craters were left by such derided bombs as Dance of the Vampire and Urban Cowboy. But when producers turn their envious eyes to the grosses from Hairspray, the exuberant version of the John Waters cult film and a heavy favorite tonight, they still want to take a chance and get into the picture.”
