The Skype Audition That Made the 'War for the Planet of the Apes' Director Cry

War for the Planet of the Apes introduced one of the franchise's most enduring characters yet, and now a home entertainment featurette is explaining a little more about how Steve Zahn's Bad Ape came to be.

In the featurette, which Heat Vision got its hands on early, director Matt Reeves explains the humanity that Zahn brought to the role.

"Not only is he incredibly funny, but he's very, very human. I knew he could do the humorous aspects of this character," said Reeves. "But I really wanted to see what he would do with the more emotional stuff."

So Reeves asked him to read scenes over Skype.

"Over Skype, which is ridiculous, he made me cry," said Reeves. "He was so connected in a real way, and was just being completely authentic."

War for the Planet of the Apes is out on digital Tuesday and Blu-ray/4K Ultra HD on Oct. 24.
