“Twelfth Night” is one of Shakespeare’s richest, most complex comedies, full of equal measures of laughter and sadness. Happily, the new Shakespeare Company’s production brings out all the depth and breadth of “Twelfth Night” in a production as visually stunning as it is verbally intense.

Directed by Rebecca Bayla Taichman, this “Twelfth Night” begins with one of its main characters falling slowly through a blue-green abyss, representing the sea. It is Viola, lost in a storm, cast up in a strange land. Believing her twin brother Sebastian to have drowned, she dresses in his clothes and becomes a servant to Duke Orsino.
