Some plays take years to write, stage, and perform. Meanwhile, the six short works at Xtreme Theatre Smackdown have all been created in 24 hours. The talented folks at Theatre Unbound, a production company that showcases women theater artists, will once again be challenging themselves to flashes of brilliance (or at least high entertainment). Their journey begins on Friday, as groups rush to write, block, memorize lines, find props, and pull together something that generally appears to be theater by Saturday night. Audiences’ only challenge should be getting to SteppingStone, where they will be treated to shorts aimed at amusing, provoking thought, or just having fun.
