"I think it's a double bump catalyst where you need both things to get her story in motion," he says of ScarJo. "If you have like three things that happen that are kind of the catalyst, well, it might get a little busy and this movie at times feels a little busy." He adds: "The good news I always say about catalyst, if you're debating that, it's better to have too many than too few"
