1. BABY MAMA
[MOVIE] Tina Fey brings the sardonic wit she has honed on NBC's "30 Rock" to her big-screen turn as a single woman determined to have a child, despite her million-to-one chances of getting pregnant. So she does what any other type-A business executive would do: She chooses a crass South Philly working girl (Amy Poehler) as a surrogate, pores over baby books and, when the surrogate needs a place to live (surprise!), lets her move in. It's "Thelma & Louise" meets "The Odd Couple," plus a baby.
2. EARTH DAY ON THE MALL
[MISCELLANEOUS] Environmental causes have never been hipper, so it is unsurprising that this celebration (two days ahead of the official Earth Day) is bigger, better and more celebrity-packed than ever. The Earth Day Network, in partnership with the Green Apple Festival, is sponsoring the event, which features musicians, politicians and other generally famous folks (such as comedian Chevy Chase). In the first group, the bill includes the Roots, Thievery Corporation, Gov't Mule, Jordin Sparks, Toots and the Maytals, and Talib Kweli. Senate Majority Leader Harry Reid, author Tom Friedman and mogul Russell Simmons will also appear. For details, see http:/
Today at noon. The Mall, between the U.S. Capitol and the Lincoln Memorial. Free.
[SPORTS] Is anyone really surprised that the Wizards are facing the Cleveland Cavaliers in the first round of the NBA playoffs? It has been only, what, three years in a row? This time, though, both squads are entering the playoffs in a very different way. In Cleveland, LeBron James isn't playing like himself as he recovers from back spasms and his team reels from a disappointing end to the regular season. Meanwhile, Gilbert Arenas is returning to the Wizards after a long break during which Caron Butler and Antawn Jamison proved their worth. We're not about to jinx anything here with a bold prediction, but the third time is the charm, right? Tickets were available at press time. Thursday's game will be broadcast on TNT, while ABC will carry the April 27 matchup.
Thursday at 8 p.m. April 27 at 1 p.m. Verizon Center, 601 F St. NW. $47 and up (way up). 202-628-3200.
4. ETRAN FINATAWA
[CONCERT] This group from the deserts of Niger claims to be the first to use the music of the nomadic Wodaabe people in a modern context. The band began as a mixed group of Tuareg and Wodaabe-Fulani tribesmen who wanted to use music to unite their two oft-feuding cultures. The touring group consists of three members of each tribe performing a hypnotic sound that has been dubbed nomad blues.
Monday at 8:30 p.m. Iota Club & Cafe, 2832 Wilson Blvd., Arlington. $15. 703-522-8340.
