10 Action Movie Mistakes You Can’t Unsee
9. The Self-Repairing Alfa Romeo - 6 Underground
6 Underground might well be the most technically sloppy film of Michael Bay's career, for while even Bay's best movies tout their fair share of mistakes, this one is littered with them in basically every single scene.
But Bay gets perhaps the most insultingly egregious, no-effort blooper out of the way in the film's first five minutes, when the neon green Alfa Romeo Giulia Quadrifoglio being driven by Six (Dave Franco) is side-swiped by an oncoming truck.
This results in the car's left wing mirror being ripped off and considerable scraping damage being done to the left side of the car, but as soon as Six drives away, the mirror is magically reattached and there's not a damn scratch on that side of the car.
Only after the car receives considerably more punishment throughout the chase does the wing mirror finally disappear again and the left side of the Alfa Romeo look suitably damaged, suggesting that Bay might've restructured the sequence during post-production.
