For "2012," Emmerich set his sites on destroying the some biggest landmarks around the world, from Rome to Rio. But there's one place that Emmerich wanted to demolish but didn't: the Kaaba, the cube-shaped structure located in the center of Mecca. It's the focus of prayers and the site of the Hajj, the biggest, most important pilgrimage in Islam.

"Well, I wanted to do that, I have to admit," the filmmaker told scifiwire.com. "But my co-writer Harald [Kloser] said, 'I will not have a fatwa on my head because of a movie.' And he was right."

Emmerich went on: "We have to all, in the western world, think about this. You can actually let Christian symbols fall apart, but if you would do this with [an] Arab symbol, you would have ... a fatwa, and that sounds a little bit like what the state of this world is. So it's just something which I kind of didn't [think] was [an] important element, anyway, in the film, so I kind of left it out."
