The 2021 production, by Keith Warner, of Handel’s Giulio Cesare in Egitto at the Theater an der Wien uses Grauman’s Egyptian Theatre as a framing device. Sometimes the action is clearly the actors, producers, cigarette girls etc involved in the screening of a silent German movie version of “Caesar and Cleopatra”. Other times they are performing the action of the film/opera. Sometimes the cinema screen shows clips from the movie. Other times it shows pictures of the characters on stage. For example, at the beginning of Act 2 Tolomeo, whose other persona is some kind of sleazy mafioso movie exec, is shooting up. There’s a B&W picture of him on the screen that slowly changes to bright colours and then becomes more and more a depiction of a pretty heavy trip.
Pietro Antonio Cesti’s 1657 dramma musicale La Dori is a hoot. It seems to prefigure every plot device that will ever be used in opera. A baby sold by bandits who turns out to be a princess. Pirates. A ghost. Mistaken identities. Swapped potions. Men pretending to be women. Women pretending to be men. Love polygons of fiendish complexity. I won’t even attempt to explain the plot because it’s very complex and silly and hardly matters. It took me a half page diagram just to map the relationships between the characters.
