Director Christopher McQuarrie also reveals the stunt that "separated the joints in Tom's fingers," of which he says, "It was so painful to watch."

Speaking with Empire, Christopher McQuarrie says “the hardest thing I’ve ever had to do” wasn’t filming the incredible biplane sequence at the end of The Final Reckoning or the beautifully put together submarine sequence.

Tom Cruise recently opened up about the intense stunt demands of filming Mission: Impossible – The Final Reckoning. In newly released bonus content, he discussed the climactic biplane sequence and how it pushed him to his physical limits.
