WHAT DO YOU GET when an aristocratic comedy of errors bodyslams into a campy martial-arts movie? “The Kung Fu Importance of Being Earnest,” naturally, part of the Brick Theater’s $ellout Festival. Two high-mannered 1890s Englishmen tangle with two scrupulously honest ladies and a shared pseudonym. When the men find themselves outwitted and tripped up by their own deceptive shenanigans, you can be sure they resort to a theatrical device Shakespeare WISHES he had for “Two Gentlemen of Verona”: kung-fu fighting. The idea was conceived by Timothy Haskell, the play adapted and directed by Michael Gardner, and the fights choreographed by Qui Nguyen. It’s being touted as zanily refreshing and strangely faithful to Oscar Wilde’s original classic, it involves both Shao Lin and a Weeble, and it’s been extended to Aug. 26.
