The film is divided into three sections with a specific time span. Mole takes place for a week, sea for a day, and air for a hour. As the scenes progress, the three stories will eventually collide, their collision affecting the lives of the primary players on scene. The primary narrative rests in the hands of Fionn Whitehead, who we meet as an English soldier running for his life when German solders attempt to shoot him and his comrades. When he reaches the trenches of the French, he eventually finds himself on the beachfront, where British and French soldiers are waiting for evacuation through sea. The Germans have them surrounded in the town of Dunkirk, and the soldiers are waiting for their salvation. The second narrative involves a father, his son and his son’s friend heading to Dunkirk to help with the soldier evacuation. The third narrative has three pilots watching out for enemy planes as they oversee the evacuation from Dunkirk beach. Veteran actors, notably Kenneth Branagh, Mark Rylance, Cillian Murphy, and Tom Hardy, helm a specific section.
There is minimal dialogue, but Nolan still manages to bring a powerful story of hope and survival through imagery and acting. He was able to portray their strength, determination, and bravery in so many scenes. Even without character development, his characters had personality, and he manages to get the range of emotions required from his actors without scenes verging to hysterics or numbness. I think the kind of acting expected from the notable names is very much present in this film. What I was on the lookout for was how the new names in acting portrayed themselves in the film. Of all the main characters, Fionn Whitehead was the one with the least number of lines, which portrays the kind of character he was. He, as well as Harry Styles did well in their roles.
This is the most straightforward film I have seen from Christopher Nolan. It's not flashy, nor talkative, but his narrative was supported with talented folks that helped make this Nolan's masterpiece.
