Matt Donnelly Senior Film Writer Aaron Taylor Johnson beamed in to Las Vegas’ CinemaCon on Monday to show the first footage from his anticipated Marvel comic book film “Kraven the Hunter” — an ultraviolent show of blood and throbbing biceps that pleased the annual convention of theater owners. Taylor-Johnson called the J.C. Chandor-directed project “a Marvel movie grounded heavily in the real world. We know he is a fierce hunter, a highly trained killer.” He then gave an answer to “the internet’s biggest question,” as to whether the film would be rated R. “Fuck yeah it will be rated R,” the star said to huge applause from the Colosseum Theater at Caesars Palace Hotel and Casino.
