Warner Bros. has staked “Get Smart” director Peter Segal and his Callahan Filmworks partner Michael Ewing to a three-year first-look deal. As part of the deal, WB has also acquired the John August-scripted “Captain Marvel”; Segal will direct the DC Comics adaptation. He and Ewing began working on the film two years ago at New Line, but the property has moved over to Warner Bros. The film tells the story of teenaged Billy Batson, who transforms into the superhero when he says the word “Shazam!”
