actor Matthew Modine made a horrifying discovery on Amazon Prime. The platform seemingly had altered the iconic poster for Stanley Kubrick’s 1987 war movie, “Full Metal Jacket,” starring Modine and Vincent D’Onofrio. The phrase “Born to Kill,” scribbled on a camo Marine helmet, was suddenly gone.The digital clean-up crew did however, keep the helmet’s peace sign; some delicate soul, it appeared, thought the words were too inflammatory to remain.
