Twelfth Night is certainly a play where mistaken identities are crucial to the plot. Viola's alternate identity as Cesario attracts Olivia, yet her real identity is attracted to Orsino. Further confusion between Cesario and Sebastian, as when Feste, Olivia, and Aguecheek mistake Sebastian for Cesario and when Antonio and Olivia (after marrying Sebastian) mistake Cesario for Sebastian pushes the plot to its conclusion through the last two acts.
Twelfth Night, Or What You Will.
She's the Man is based on Twelfth Night. The twins are named Viola and Sebastian. The characters Duke, Olivia, Andrew and Toby also appear in both the play and the movie. The plot is also the same; the female twin disguises herself as the male twin and a case of mistaken identity ensues.
