In A Bug’s Life, the circus ringmaster is a flea. It’s a flea circus.
Admittedly I had heard the term “flea circus” my entire life but only this morning looked up what it actually was. I mean it’s pretty straightforward, a bunch of fleas made to look like they’re in a circus, but I was missing the history and context.
It took me several viewings of Hot Fuzz to realize that the pair of shotguns PC Angel has strapped to his back in the climax of the film are meant to evoke angel’s wings.
