Twelfth Night is a comedy by William Shakespeare, named after the Twelfth Night holiday of the Christmas season. It was written around 1601, and was first published in the First Folio in 1623.

Twelfth Night: Or What You Will is a 1996 film adaptation of William Shakespeare's Twelfth Night, or What You Will by director Trevor Nunn. The adaptation is set in the early 19th century.

Viola and Sebastian are lookalike twins, separated by a shipwreck. Viola lands in Illyria, where she disguises herself like her brother and goes into the service of the Duke Orsino. Orsino sends her to help him woo the Lady Olivia, who doesn't want the Duke, but finds that she likes the new messenger the Duke's sending. Then, of course, Viola's brother shows up, and merry hell breaks loose. Meanwhile, Olivia's uncle and his cohorts are trying to find some way to get back at Olivia's officious majordomo, Malvolio.

Brother and sister Viola and Sebastian, who are not only very close but look a great deal alike, are in a shipwreck, and both think the other dead. When she lands in a foreign country, Viola dresses as her brother and adopts the name Cesario, becoming a trusted friend and confidante to the Count Orsino. Orsino is madly in love with the lady Olivia, who is in mourning due to her brother's recent death, which she uses as an excuse to avoid seeing the count, whom she does not love. He sends Cesario to do his wooing, and Olivia falls in love with the disguised maiden. Things get more complicated in this bittersweet Shakespeare comedy when a moronic nobleman, Sir Andrew Aguecheek, and a self-important servant, Malvolio, get caught up in the schemes of Olivia's cousin, the obese, alcoholic Sir Toby, who leads each to believe Olivia loves him. As well, Sebastian surfaces in the area, and of course there is Feste, the wise fool, around to keep everything in perspective and to marvel, like we the audience, at the amazing things happening all around.
