Skillet Productions' tragicomic exploration of a dissolving showbiz duo exceeds Atom Egoyan's 2005 film on the same subject, Where the Truth Lies. Writer-performers Dave Lykins and James Yeater are superb as a 60s-era comedy team between sets at a Catskills club, abusing and placating each other by turn. The dialogue is natural, the two have a war-buddies rapport, and director Don Hall keeps the tension high. But a brilliant prop upstages everything else in the production: an empty frame, suspended from the ceiling downstage, serves as a vanity mirror. Usually watching each other's "reflections" in it while they talk, they not only speak directly to the audience but reveal the distance that's grown between them, two phantoms in a bright-lights fantasy. Through 4/8: Fri-Sat 8 PM, Town Hall Pub, 3340 N. Halsted, 773-345-0726, $10, 21+.
