2010 is a big year for the Washington Shakespeare Company, a playhouse dedicated to presenting classical theater in bold and innovative ways. This year marks WSC’s 20th anniversary and a change in venue, as it moves from Crystal City to its new digs in Rosslyn’s Artisphere complex. WSC will celebrate these events on Saturday at the Rosslyn Spectrum with a gala that includes a one-night-only staging of By Any Other Name: An Evening of Shakespeare in Klingon. The event will feature a special appearance by George Takei, who played Sulu in the original Star Trek series and several of the feature films.
