Shouldn't the 5th line be:

angular.module('popcornApp, [])

If you're copying the contents into app.js, like I was in the beginning of the tutorial, then the empty array is required. However towards the later stages, the controller is moved into a file of its own, just as its listed in the first line. At that point the empty array isn't required as it is employing the setter method. The former, on the other hand is a getter method as elaborated by Nate in the tutorial.
