In Sing 1 and 2, Matthew McConaughey plays Buster Moon, a koala who is obsessed with musical theater and determined to make it in show business.

It's Buster who holds a singing competition and discovers talented animals in his town including Rosita, a housewife voiced by Reese Witherspoon, Johnny, a teen gorilla voiced by Taron Egerton, and Meena, an elephant voiced by singer Tori Kelly.

The group of talented animals quickly becomes popular, but Buster has higher aspirations for his talent, which is the premise for Sing 2. The group finds themselves putting together a show for entertainment mogul Jimmy Crystal (Bobby Cannavale) in Redshore City, the equivalent of Las Vegas IRL.

As expected, they take Redshore City by storm, showing that the sky's the limit for the group, and why it's no surprise that Matthew McConaughey is ready to return for another movie.

When asked why his character didn't have a musical number in Sing 2, the actor told CinemaBlend in December 2021: "Maybe Sing 3, but it wasn’t in this one and a lot of people have been saying that and I’m like that’s right, Buster Moon should sing, whistle, diddy, hum, dance, something. Oh, that’d be super fun. That could be it. Bring it up to the director, I’m with you. You hear that, Garth [Jennings]?"
