Tenet's trailer had dropped some time back and wowed audiences like never before in which we see a plane being crashed into a building deliberately towards the end. Director Christopher Nolan has said that he and his crew blew up a real Boeing 747 for the film because it was "more efficient" than practical effects using miniatures or CGI.
"I planned to do it using miniatures and set-piece builds and a combination of visual effects and all the rest. However, while scouting for locations in Victorville, California, the team discovered a massive array of old planes," he was quoted as saying in an interview.
"We started to run the numbers … It became apparent that it would actually be more efficient to buy a real plane of the real size, and perform this sequence for real in camera, rather than build miniatures or go the CG route," he added.
"It's a strange thing to talk about – a kind of impulse buying, I suppose. But we kind of did, and it worked very well, with Scott Fisher, our special-effects supervisor, and Nathan Crowley, the production designer, figuring out how to pull off this big sequence in camera. It was a very exciting thing to be a part of," he further said.
"It's so bold to the point of ridiculousness," Robert Pattinson, who stars in the film was quoted as saying.
Watch the trailer and look for the scenes towards the end.
