Ed Villarreal, Tristan Tapscott, and Bryan Tank in The TempestDirector Chris Causer plays up the baser parts of William Shakespeare's The Tempest in the District Theatre's latest production, taking the debauchery of Bryan Tank's Trinculo, a coxcomb of a servant, and Ed Villarreal's Stephano, a drunken butler, to their limits. (And sometimes mine.) The scenes involving the two men bickering, and their leading around of Todd Schwartz's crazy-ish castaway Caliban - a native to the island that serves as the play's setting - drew large laughs from Friday's audience, and broke up the serious tone of the rest of the tale.
