Tom Cruise is bringing more death-defying stunts than ever before to In a new behind-the-scenes clip from the upcoming action flick, Cruise and director Christopher McQuarrie headed to the Lake District in northwest England to film the franchise star participating in «one of the most dangerous sports in the world,» speedflying. «While it may look similar, speedflying is not skydiving,» McQuarrie explains in the clip. «Skydiving is fairly predictable, speedflying is incredibly unpredictable.»While skydivers look for an open field to land in comfortably, for speedflyers, the point is to accelerate and spiral as close as possible to the mountains and rock formations — just feet off the ground — before landing at a high rate of speed.The intense scenes were too dangerous to film with a helicopter or drone, so the crew had to construct their own gimbal system, rigging up two cameras to track Cruise's rapid descent down the mountains, reaching speeds of up to 50 miles per hour.«It is truly a one-of-a-kind adventure,» McQuarrie says in the clip of directing Cruise through his increasingly daring stunts in thefilms.
