As filmmaking evolved in the late 20th and early 21st centuries, so did the idea of the movie musical. While Disney remained at the forefront of the field with animated mini-epics like The Lion King and Frozen, other players entered the game to thrilling results. New adaptations of Broadway sensations like Cats and Rent introduced chestnuts like “Memory” and “Seasons of Love” to brand-new audiences; Mamma Mia! and other jukebox musicals allowed A-listers like Cher to put their stamp on pop classics; and Once and La La Land were among the movies that melded musical numbers with indie-film ideals.
