One idea of "secret theater" is that we don't know where the performance is until we're escorted there, or the nature of it until we get there.
So we walked up Girard Avenue and along Second Street to the site - Go ahead! Threaten me! I'll never give it away! This is dinner theater, of a sort, and once there, we were greeted by Antony and Cleopatra-themed centurions serving little cups of real mint juleps and nonalcoholic ones, too, plus mini-cupcakes. And then the show began.
With due respect to William Shakespeare, Antony and Cleopatra is an unproduceable, 3,600-line mess with an enormous number of scenes, some lasting seconds. It's rarely performed. You either have to boldly reduce it to get to the tasty sauce (the Pennsylvania Shakespeare Company's way, triumphantly, a few seasons back) or pretty much rewrite the thing (Missoula Oblongata's way, a bizarre, workable, and altogether goofy success).
I am not going to give away the various punches of this particular Antony and Cleopatra, except to say that its fringe quality gives the play some nice turns; that it's about 30 percent Shakespeare and the rest free-range interpretation; that it rambles intentionally, in theatrical styles and in different rooms; and that it comes complete with a different dessert from five Philadelphia neighborhoods with each of its five short acts.
The play itself is done by five different theater companies, one per act; some acts are better than others, and if you don't like one act, wait a few minutes - another is coming. The last act gives the play a modern, feel-good slant, something Richard Burton and Elizabeth Taylor would have done well to consider when they took the roles in the movie Cleopatra.
