It's morning in America--and the Reagan administration is responding ever so slowly to a public health crisis: a virus that has targeted the gay community. In Tony Kushner's sprawling, caustic and moving two-part epic, Angels in America , people from all walks are confronted with the political, ethical and spiritual consequences of life during a time of plague. Duke Theater Studies presents Kushner's work in toto over the next month--in limited one-week showings in smaller rooms on campus. Jeff Storer begins the series with Millenium Approaches, Wednesday through Sunday in Sheafer Theater. Tickets are $10 and $7; call 684-4444.
