Watch full movie online. Twelfth Night is a rousing contemporary musical adaptation of Shakespeare’s classic romantic comedy about mistaken identity and self-discovery. On the twelfth day of Christmas, shipwrecked Viola washes up on the shores of Illyria, disguises herself as a man, is sent to court a countess and falls hard for a Duke. As she navigates the gender confusion in all her roles, she finds her true self and true love in the process. Featuring an original jazz-funk score by Shaina Taub, Twelfth Night is a soulful shake-up of a Shakespearean classic, perfect for the 12th night of Christmas or any day of the year.
