From Disney's press materials: "The BFG unites the talents of three of the world’s greatest storytellers - Roald Dahl, Walt Disney and Steven Spielberg - to bring to life the classic tale of a courageous little girl named Sophie (newcomer Ruby Barnhill) and a gentle and charming Big Friendly Giant (Oscar®-winner Mark Rylance) who introduces her to the wonders and perils of Giant Country. Spielberg employs a new, hybrid style of filmmaking blending live-action and performance-capture techniques, resulting in genuine, heartfelt performances and super-photorealistic animation.
Spielberg’s directorial debut with The Walt Disney Studios was a labor of love, as he’s been a fan of Dahl’s for years. In fact, he read The BFG to his own children when they were younger. According to Spielberg, 'It’s a story about friendship; it’s a story about loyalty and protecting your friends; and it’s a story that shows that even a little girl can help a big giant solve his biggest problems.' The BFG is a Golden Phizzwizard* come true for Spielberg, Dahl fans and audiences around the world."
