Toads, hedgehogs and turtles star in the nocturnal opera, which is conducted by a rather beautiful CGI squirrel.
The music is ‘Squilla il bronzo del dio… Guerra, guerra', the great chorus from Vincenzo Bellini's opera Norma.
In an interview with Vimeo, the film's director explains why they chose the chorus:
“We spent two weeks listening to opera songs and ended up with this track from the famous Bellini opera Norma called ‘Guerra Guerra,' which is a war anthem.
“The track had the epic, explosive vibe we wanted, and a female singer, which was necessary for the bird character.
“So, if you're wondering what these animals are singing, they're basically preparing the revolution!”
