These two -- otherwise, rather strange bedfellows -- are starring in the Woody Allen movie Cafe Society, which was the opening film at Cannes. I have created an entire story in my mind about how they were primed to hate one another, but Blake's cake-pop-baking enthusiasm won Kristen over, and Kristen's wry slouchiness gave Blake a little edge, and they ended up being fast friends who had a lot of fevered conversations about whether or not they regret working with Woody Allen.
