This is an alternate ending of the movie The Lion King. Indeed, this was the ending in the earlier production of the movie; however, producers alternated this ending as this first one was too horrific for a Disney Film and letting Scar be mauled by his hyena henchmen was more interesting to Scar's death than simply having him burn to death as he did in this version. Ironically, the final scene was in fact based on an alternate ending of Beauty and the Beast where Gaston was killed by Wolves, which was cut for the same reasons this ending was cut (i.e. it was too graphic for a Disney film).
