Director Marc Webb, whose previous big-screen foray was the romantic (500) Days of Summer, explains, "When we tested them, there was fireworks. She could take on Andrew's improvisation and witticisms and one-up him. I mean, it was amazing to see them go back and forth. … It became an obvious combination, because that's what people are there for."
And Emma adds, "Marc Webb's biggest goal has been working out that relationship, and making sure it feels authentic, and he kind of brings it all back down to earth, even though we're operating in a superhero universe. It's certainly important to Andrew and I that this relationship would exist in a world of no superheroes."
