He ain’t Jordan Catalano no more. To play John Lennon’s pudgy assassin, Mark David Chapman, in the 2007 film Chapter 27, the usually svelte Jared Leto gained an impressive 67 pounds through a diet that was just, well, gross. “[I did it by] eating everything you think you're not supposed to—pizza, pasta, ice cream, but my little trick was I would take pints of chocolate Häagen Dazs and put them in the microwave and drink them,” Leto told Starpulse. But the grossest part? “The sick thing is, I would actually pour olive oil and soy sauce into the mixture as well—to get me bloated even more,” said Leto. Sadly, it was mostly for naught—the film grossed only $56,215 in North America, and received mostly negative reviews.
