* ActingForTwo: The 1969 version. Joan Plowright did the parts of both Viola ''and'' Sebastian, thus reversing the original Globe Theatre custom. Plowright then cross-dressed in a male role, as well as playing the girl who cross-dressed to pass for a man.
* RealitySubtext: If one takes the interpretation that the death of Shakespeare's son Hamnet affected his works, the happy reunion of Sebastian and Viola can be seen as his wish for Hamnet to be happily reunited with his twin sister, Judith.
