Sing took place in a world of anthropomorphic animals, where Buster Moon, a theater owner, hosts a singing competition so he can solve his financial troubles.
The ensemble cast included Matthew McConaughey as Buster Moon the koala, Reese Witherspoon as Rosita the pig, Scarlett Johansson as Ash the porcupine, Seth MacFarlane as Mike the mouse, John C. Reilly as Eddie Noodleman the sheep, Taron Egerton as Johnny the gorilla and Tori Kelly as Meena the elephant.
With Sing 2 so far away, it will be a long time until we learn specific plot information, but for now, two things are still guaranteed: plenty of animals and plenty of covers of popular songs.
