The movie takes place 15 years after the siblings' incident at the gingerbread house. Arterton explains: "You see a series of flashbacks with their experience of killing that first witch, which is brilliant... The heart of it is that these kids grow up to be bloodthirsty witch hunters."
She added that, while the film is a bit tongue in cheek, "it's also very, very dark, and bloodthirsty and there's a lot of cursing. It's kind of got a [Quentin] Tarantino feel, really."
So what are the characters like in the movie? "Gretel is much more in tune with her spiritual side. Hansel is a typical action hero, cheeky, funny, a womanizer. She's much more of a thinker, intense, internal and bit more open-minded than he is."
