We've got to hand it to Carolina Actors Studio Theatre for scrapping what was beginning to look like annual holiday stagings of A Tuna Christmas. The popular holiday production is finally being bumped this year for Moises Kaufman's 33 Variations, which runs Nov. 23 through Dec. 23. But there's nothing fishy about the works of Kaufman - a playwright, director and founder of Tectonic Theater Project in NYC - whose more serious productions include Gross Indecency: The Three Trials of Oscar Wilde and The Laramie Project, a play about the late Matthew Shepard (an openly gay student at University of Wyoming who was brutally murdered in 1998).
