This filmed production from 1957 of the play from the Stratford Festival almost defies explanation. Here are your three reasons:

1. One of the masked chorus people is actually William Shatner, pre-trekking any stars. Play Guess the Shatner throughout!

2.The over-acting is taken to levels previously unknown to humanity. As an example, when Oedipus finds out he accidentally killed his father, he performs a move that has become classically known as the angry skier, shrieking and flailing like a macaque on acid, then just stops like nothing happened. Also, he appears to be wearing the world's largest macaroni necklace (or possibly croissants).

1. Additionally, the chorus members have nightmare-inducing masks, the weirdest vocal intonations in history, and a disturbing tendency to stare at the audience or fall over for no reason (they may have been wearing stilts in some cases).

Enjoy, and may you not be haunted forever in your dreams by freakishly masked weirdos with a bad case of vertigo.
