NEW YORK — Joel Schumacher, the eclectic and brazen filmmaker who dressed New York department store windows before shepherding the Brat Pack to the big screen in “St. Elmo’s Fire” and steering the Batman franchise into its most baroque territory in “Batman Forever” and “Batman & Robin,” has died. He was 80. A representative for Schumacher said the filmmaker died Monday in New York after a yearlong battle with cancer. A native New Yorker, Schumacher was first a sensation in the fashion world after attending Parsons School of Design and decorating Henri Bendel’s windows.
