Is John Wick Invincible? Director Shoots Down Claim in Behind the Scenes Clip

Keanu Reeves' John Wick may be the most effective assassin on the face of the planet, but he's also a mortal human being like the rest of us. The thing that sets him apart? An iron constitution on par with that of a literal god.

"We always say in John Wick, with the martial arts, it's not the gun or the stick or the knife or the sword that's an extension of your arm — it's an extension of your will," franchise director Chad Stahelski declares in a behind-the-scenes look at the Chapter 4 home release (now available on Digital). "And if there's one word that would describe John Wick, it's 'willpower.' The guy will not stay down ... He's not indestructible. He just gets up. If he gets knocked down a thousand times, he gets up a thousand and one."

Nowhere is Mr. Wick's unparalleled determination more evident than in his relentless battle up and down — and then up again — the hundreds of stairs leading to his sunrise duel with the Marquis Vincent de Gramont (Bill Skarsgård) at Sacré-Cœur in Paris. Oy, our knees ache just thinking about.

"There's so much to play with," stunt coordinator Stephen Dunlevy says of the memorable set piece. "We have ramps on the sides with trees. There's people getting shot and getting tripped off ramps and trees and down railing and over the sides."

In addition to both theatrical trailers, here are the bonus features that await you in all versions of the Chapter 4 home release...

The Blind Leading the Fight: John Wick: Chapter 4 witnesses the arrival of Caine, a blind killer played by legendary actor and martial artist Donnie Yen. With a style not seen since The Blind Swordsman: Zatoichi, Caine shows that a killer’s greatest instincts come not from his eyes, but from his mind.
