The sequel to Sing (2016), it was written and directed by Garth Jennings, co-directed by Christophe Lourdelet, and produced by Chris Meledandri and Janet Healy.

The sequel also features new characters voiced by Bobby Cannavale, Bono, Halsey, Pharrell Williams, Chelsea Peretti, Letitia Wright, and Eric André.

Sing 2 made its world premiere at the AFI Fest on November 14, 2021, and was theatrically released in the United States on December 22, 2021.

Buster Moon is thriving with his newly rebuilt theater; Johnny, Meena, Rosita, Gunter, and Miss Crawly work as his cast and crew, while Ash performs as a soloist at a rock club.

As Jimmy is uninterested in Buster's original show pitch, Gunter suggests a space-themed sci-fi musical that features songs from Clay Calloway, a legendary rock star lion who disappeared after his wife Ruby died 15 years prior.

Intrigued, and assuming that Clay will be a part of the show, Jimmy greenlights it and lets Buster and his friends stay at his hotel during production.

During rehearsal, Rosita develops a fear of heights after discovering she needs to make a high jump, prompting Jimmy to insist Buster have his daughter Porsha play her part instead.

Meena is cast in a romantic scene with Darius, an egocentric actor yak, but is unable to act the part convincingly, having never been in love before.

After news of the "firing" is broadcast on television, an outraged Jimmy nearly drops Buster off the roof of the hotel, before locking him in a closet.

Porsha rejoins the show, Johnny summons his father's gang who are now released from prison on community service to keep Jimmy and his bodyguards at bay, and Rosita arranges for her husband Norman and their children to distract hotel security.

Porsha performs a high energy song and dance number in the minor role originally given to Rosita, standing up to her enraged father.

As with the first film, Jennings' filmmaker friends Wes Anderson, Chris Renaud, and Edgar Wright all have cameos in the film, with Anderson as a tarsier night cleaner,[11] Renaud as Linda Le Bon's show announcer, and Wright voicing a dog cop and a pig chauffeur.

[12] Scott Mosier, director of The Grinch and the short film Eddie's Life Coach, voices Mason, a walrus worker making the sets for the show.

Writer/director Garth Jennings and producers Chris Meledandri and Janet Healy return along with voiceover stars Matthew McConaughey, Reese Witherspoon, Scarlett Johansson, Nick Kroll, Taron Egerton and Tori Kelly.

[13] In December 2020, Bobby Cannavale, Letitia Wright, Eric André, Chelsea Peretti, longtime Illumination collaborator Pharrell Williams, Bono and Halsey were added to the voice cast.

Overall, the film had a better social media reach than 2021's Encanto, The Addams Family 2, Tom & Jerry, Spirit Untamed, and The Croods: A New Age.

[53] In its fifteenth weekend, the film added $3 million to its total gross and the Sing franchise as a whole passed the $1 billion mark.

The site's critical consensus reads, "Second verse, same as the first: For audiences that enjoyed the first installment, Sing 2 should prove another endearing diversion.

[61] Peter Debruge, of Variety, also gave a positive review, saying the film is "an elaborate machinery of joy, and it's easier to appreciate how every choice seems designed to put a smile on people's faces".

Emily Clark of Plugged In praised the film's inspiring and emotional elements, but took issue with the fact that Meena "clearly tells Buster she's not OK kissing someone on stage, and he sort of dismisses her...The whole affair made me a bit queasy thinking about how many a young starlet has received her first smooch from a total stranger at the behest of adult directors and producers.
