Shakespeare's great festive comedy, probably written and first performed around 1601, follows the adventures of twins Viola and Sebastian, who are separated from each other by a shipwreck. Viola, believing her brother dead, disguises herself as a page in order to serve the lovesick Duke Orsino, who has been rejected by the Countess Olivia. The ensemble cast includes a roster of wonderfully comic characters: Olivia's drunken uncle Sir Toby Belch, his foolish friend Sir Andrew Aguecheek, the witty serving woman Maria, the social-climbing steward Malvolio, and the clever, riddling clown Feste.
