Disney concluded a three-hour presentation at D23 on Friday, August 9 with a trailer for “Mufasa: The Lion King.”

The upcoming prequel to 2019’s The Lion King explores a more innocent side of Mufasa and Scar before their brotherhood turned into a deadly rivalry that ended with the tragic death of the former.

Check out the newly released footage below and read on to learn more in detail.

It’s safe to say that Mufasa: The Lion King will make the tragic ending of The Lion King even more heartbreaking.

The film, directed by Oscar-winning director Barry Jenkins (Moonlight), begins with Rafiki (the baboon) telling the legend of Mufasa to his granddaughter Kiara. According to the trailer description, the story is told in flashbacks, and the images we see in the footage confirm this.

We see Scar, whose real name is Taka, rescue the orphaned cub from the alligators before introducing him to his royal family, who are very reluctant. The brothers nevertheless go on to have fun adventures of their childhood and young adult lives, with Scar telling Mufasa that he always wanted a brother.

Just in time for the occasion, the future disgraced lion makes his statement in the form of a song written by Lin-Manuel Miranda called “I Always Wanted a Brother.” The songwriter and actor revealed at D23 that he was writing Encanto when he received the script for Mufasa and couldn’t turn down the project.

Aaron Pierre and Kelvin Harrison Jr. voice Mufasa and Scar, respectively, alongside Billy Eichner and Seth Rogen, who return as the voices of Timon and Pumbaa. Blue Ivy Carter takes on the role of the voice of Kiara, while her mother Beyoncé returns to play her on-screen mother Nala.

“Mufasa: The Lion King” is scheduled to hit theaters on December 20. A prequel trailer for the film was also released in April.
