The debut teaser for Steven Spielberg’s feature adaptation of Roald Dahl’s classic The BFG has dropped today courtesy of Disney. In the clip above, we meet Sophie (newcomer Ruby Barnhill), who takes us through the rules for witching hour — which, contrary to popular belief, she says, falls at 3 AM. “Never get out of bed. Never go near the window. Never look behind the curtain,” she says. But then she does. And we get the first look at Mark Rylance — or at least a sizable part of him — as the titular Big Friendly Giant.

bfgbookThe story sees the BFG introduce Sophie to the wonders and perils of Giant Country. He’s 24 feet tall and endearingly dimwitted. He keeps to himself for the most part, unlike Bloodbottler (Bill Hader) and Fleshlumpeater (Jemaine Clement), who are twice as big and at least twice as scary and have been known to eat humans. Sophie initially is frightened of the BFG but comes to realize he is actually quite gentle and charming. Having both been on their own in the world up until now, their affection for each other quickly grows.

But Sophie’s presence in Giant Country attracts the unwanted attention of the other giants, who have become increasingly more bothersome. The pair soon depart for London to see the Queen (Penelope Wilton) and warn her of the precarious giant situation, but first they must convince the Queen and her maid, Mary (Rebecca Hall), that giants do indeed exist. Together, they come up with a plan to get rid of the giants once and for all.

Spielberg says, “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 late Melissa Mathison adapted Dahl’s book for the screen. The film is produced by Spielberg, Frank Marshall and Sam Mercer, with Kathleen Kennedy, John Madden, Kristie Macosko Krieger, Michael Siegel, Frank Smith and Naia Cucukov serving as executive producers.

The BFG opens domestically on July 1; the international rollout starts in late June.
