Fan Casting Captain Marvel: Gift From the Gods

Young runaway orphans Billy Batson and his sister Mary are sent to another foster place, where they make friends with school janitor Dudley H. Freeman and his crutch-bound nephew Freddy. While protecting a kid from bullies, Billy stumbles onto a magical cave where he meets the wizard Shazam who sought him as a new apprentice. He endows Billy with the powers of Greek gods Solomon, Hercules, Atlas, Zeus, Achilles, and Mercury, turning him into a powerful fully grown costumed man dubbed Captain Marvel, who can transform back and forth by speaking the wizard's name. But when the wizard is wounded by a mad scientist and an intelligent caterpillar with means of his power, Billy realizes he needs the help of Mary, Freddy, Dudley, and a talking tiger to combat them, along the way becoming a family.
