Dionysus in '69 (1970) review

One of De Palma's earliest big-screen efforts - which he co-directed with Fiore and Rubin - is a split-screen film covering the last two shows of The Performance Group's highly experimental adaptation of Euripides' The Bacchae, with William Finley playing the part of Dionysus - the left side of the screen follows the actors and actresses while the right shows the audience (although there is cross-over).  It's an audacious and in-your-face interpretation of the play but those unaware of the source material will most likely be totally befuddled - more often than not it comes across as a crazed orgy without the penetration - as the cast bounces around, shouts and gets uncomfortably close with the spectators, with their antics muddling the narrative.  It's worth taking a look at as a time capsule - there's a political message in there as well - and as an example of how to make the theatre dangerous again.
