This is it. This is the week feared by everyone. The last week of the Broadway Tony season overlaps with the Tribeca Film Festival. Plus, other movies are opening, celebrities are all over town, and there’s a major event at Lincoln Center tonight. Barbra Streisand gets the Chaplin Award from the Film Society tonight at Avery Fisher Hall. Former president and rock star Bill Clinton is presenting her the award. Both Tony Bennett and Liza Minnelli are set to perform. It’s going to be wild. At the same time, there’s an event cross town for “Mad Men” from BAFTA (or batty, depending on how you read it) New York with most of the cast including Jon Hamm, John Slattery and Christina Hendricks, plus Matthew Weiner. On Broadway, Scott Rudin and Jean Doumanian are opening “Testament of Mary” with Fiona Shaw, said to be just great. The advance word is sensational. Plus, I’ve heard there’s a premiere for Mira Nair’s “The Reluctant Fundamentalist” somewhere Monday night. Yes, April 22nd is Earth Day, but a lot of pollution will be created as limos criss-cross midtown all night. Too many choices!
