“I think it was one of the first books that I read by myself in my head,” says award-winning actress Rebecca Hall about the Roald Dahl book Steven Spielberg is bringing to the big screen. “I believed when I was nine years old that I was Sophie, the little girl.”

One of the out-of-competition Hollywood highlights here on the Croisette is DreamWorks/Disney’s The BFG which doesn’t hit theaters until July 1 stateside. The film makes its world premiere at the Grand Lumiere Theatre tonight at 7PM Cannes time. Hall plays Mary, the Queen’s lady in waiting, a personal assistant/right hand person of sorts. She’s around when Sophie shows up with a friendly giant who is seen as an outcast by his larger peers because he doesn’t gobble up girls and boys.

Spielberg specifically requested Hall for the role. On how the filmmaker works with actors, Hall says, “He’s very intuitive. He’s painting a picture. He knows down to the minutiae, down to every little movement, every little gesture, how the camera will pick up on it, what will be covered, he knows all that in his head.”

On October 14, Hall stars in The Orchard’s Christine, the Sundance Film Festival hit, as the 29 year old news reporter who committed suicide on live TV in 1974. Deadline sibling Variety reviewed Hall’s turn as “electric in the best role she’s yet been offered”.
