This child is the actor from Dunkirk, I really liked him there. Here is also great, I hope his career is full of interesting projects. I'll have him in my sights to see how he matures as an actor. We need more "restrained" actors (like Tom Hardy) and less exaggerated actors, but with good corporal expression.
