Branagh and casting director Lucy Bevan met with over 1,200 individuals for the role before landing on Shaw, who will be making her feature debut.
Branagh is also producing the pic with Judy Hofflund.
Josh Gad has also signed on to star, joining Judi Dench, who had previously been announced. Lara McDonnell has been cast in the role of Captain Holly Short, the elf hero, and Nonso Anozie will play Butler, Artemis Fowl’s formidable bodyguard.
Written by Eoin Colfer, the children’s books follow the brilliant and cunning 12-year-old eponymous criminal mastermind Artemis Fowl II, whose plot to extort gold from the secret Fairy People puts him directly in the crosshairs of some of the most dangerous creatures on earth. Over the course of the book series, Fowl becomes an antihero rather than a full-fledged villain, often working together with the fairies to stop a slew of treacherous megalomaniacs.
Irish playwright Conor McPherson is on board to pen the script. Disney recently dated the film for Aug. 9, 2019.
Tendo Nagenda and Chaz Salembier are overseeing the movie for Disney. Production is expected to start in 2018 in the U.K.
