Shakespeare wrote about "Henry V" centuries after his reign, and turned the king into a sort of superhero who could do no wrong, Branagh says.
"We know that we're interested in superheroes, kings, gods, because of their sort of human-like failings. So it seemed to me not as much of a stretch as some people might think," Branagh said at last week's Comic-Con, where he presented footage from the film. "The stretch part of it is embracing the whole world of digital effects. That's been something I've just loved because it's _ if you can think it, they can do it. And that's exciting."
