Asa Butterfield: Shooting 'Ender's Game's' ending was 'the hardest part'

Asa Butterfield has a big responsibility on his shoulders with the adaptation of "Ender's Game." He has the job of bringing Ender Wiggin to life on the big screen, something the novel's author Orson Scott Card previously called impossible.

Zap2it had the chance to catch up with Butterfield at San Diego Comic-Con and ask him how he prepared for the role. "I read the story. I'm a big fan of science fiction," he says. "Ender's character, yes he is the hero of the film, he's the savior of this science fiction epic film, but there is a lot more to him than that. In fact, that's one of the things I love about the script so much, because he's so complex and there's so much to him. It's really interesting for me."

Producer Roberto Orci confirmed to Zap2it that the ending of "Ender's Game" will remain the same in the movie as it is in the book. Butterfield discussed shooting that scene and how it affected him.

"The scale of the film is still the same and the ideas and the morals are still intact, and I think those are the key things of the book," he says. "Shooting that was probably was the hardest part about filming, and it was near the end of filming. It was hard and reading the book gave me a lot of insight and ideas about how to play it."

"Ender's Game" is due in theaters on Nov. 1, 2013.
