We had a couple of days when we were shooting these scenes, where we had massive rain towers [raining down on us]. For some reason these rain towers, [the water] is so cold. It’s so cold! And the rest of us, we get the rain on us, but we also have clothes on. And then we get a warm, cozy coat to put on in between. But because Margot [as Harley Quinn] is in full body paint, she’s just standing there taking it. And then she can’t wrap herself in anything. And you just see her, her whole body is just shivering, her teeth are clattering. And then, as soon as it’s, ‘Action,’ she’s on, and it’s on. And then you go back to in between [takes], and she’s shivering and clattering her teeth. She’s a savage.
