“Wrestling with Angels: Playwright Tony Kushner” (3 a.m., PBS): Tony Kushner has emerged

“Wrestling with Angels: Playwright Tony Kushner” (3 a.m., PBS): Tony Kushner has emerged as one of the nation’s leading playwrights (“Angels in America”). He is known for a cutting wit, trenchant observations and a tendency to address topics that are often important yet disturbing. A new documentary, “Wrestling with Angels: Playwright Tony Kushner,” reveals him as resolutely upbeat, steadily productive, and amazingly relaxed for someone whose days are driven by the urge to speak the truth, and are fueled, in part, by his background as a gay progressive who grew up in the South. Kushner emerges as an artist who, despite obsessing over themes as uncomfortable as war, race, AIDS and gay rights, nonetheless struggles to reach a popular audience — and does. Made by the Oscar-winning Freida Lee Mock, the film includes performances and readings from Kushner’s plays and musicals, with appearances by actresses Marcia Gay Harden, Meryl Streep, Emma Thompson and Tonya Pinkins, directors Mike Nichols, George C. Wolfe and Oskar Eustis and writer/artist Maurice Sendak.
