Matt's jumpsuit was set ablaze -- the back of it, anyway -- while filming scenes of his new flick "Ford v. Ferrari" at a private airport outside of L.A. You can see a stunt coordinator apply the final touches on Matt's neck, back and ass.

Matt -- who plays the late race car driver/designer, Carroll Shelby -- then jumps into his classic whip before he and the car burst into flames. Matt, of course, was all good. He later gives 2 thumbs up. That's Hollywood magic, baby.
