Tips: "Before I eat, I ask, 'Do I really want or need this, or would I be full with some chicken and veggies?' Or, 'How will I feel onstage after I eat a pizza the night before?' I try to realize when I'm thirsty versus hungry, which happens a lot!
The other thing the films have in common is Gerard Butler, increasingly a force of Nature if not exactly a subtle one: "I don't know about you, but I'm thirsty as f**k!" he declares at one point, and gulps down a full glass of water in a scene that has no narrative function except to illustrate his animal energy.
