Gad is no stranger to starring in family-friendly movies, previously lending his talents to Frozen, Beauty and the Beast and The Angry Birds Movie.
Judi Dench has primarily stuck with content geared towards adult, though she did appear in last year’s Miss Peregrine’s Home for Peculiar Children.
Judi Dench has been cast as Commander Root, the commander of the fairy police force known as LEPrecon, while Josh Gad will play Mulch Diggums, a kleptomaniac dwarf who works for the fairies, but mainly looks out for himself.
Hitting many of the same beats as the original Artemis Fowl book, the movie will follow the eponymous protagonist, a 12-year-old genius, caught up in a battle of strength and cunning against a powerful and hidden race of fairies who may be behind his father’s disappearance.
