A lion who would change our lives forever. #Mufasa: The Lion King, in theaters December 20.

“Mufasa: The Lion King” enlists Rafiki to relay the legend of Mufasa to young lion cub Kiara, daughter of Simba and Nala, with Timon and Pumbaa lending their signature schtick. Told in flashbacks, the story introduces Mufasa as an orphaned cub, lost and alone until he meets a sympathetic lion named Taka—the heir to a royal bloodline.
