The old girl's got a lot of life in her yet. Built in 1959, designed by Frank Lloyd Wright, the creamy layered wedding cake of a theater building on Turtle Creek has lately been home to some spectacular new productions. Uptown Players now do all their shows there, having learned in recent seasons how to handle the stage's balky revolve and how to complement its curves and acute angles. It is a friendly hug of a theater space, with the best acoustics in town. And no matter where you sit in the 400-seater, the view is fine. The best event there this year was Dallas Theater Center's musical Fly by Night, an intimate, magical piece with a small cast, a tight little band and simple scenery. The warmth of Kalita was perfect for that show, which would have been swallowed by the cold, cavernous Wyly Theatre downtown. Now owned by the city, Kalita Humphreys desperately needs an interior makeover: new carpets, fresh paint, reliable air conditioning (Uptown has struggled through some performances sans air this summer). Can't someone Kickstart a fund for keeping Kalita cool?
