One of the Indian participants described the length of the actual fighting as “the time it takes a hungry man to eat a meal”. I think it was all over pretty quick.

I loved “Dunkirk”, but I think many people didn’t get that it took place in three timelines - a week on the beach, a day on the boats, and an hour in the Spitfire. Classic Christopher Nolan, who loves to play with time - Memento, Inception, Interstellar. He’s not going to spoonfeed you - either keep up or get left behind.

I’d love to see his take on the Little Bighorn, along the lines you suggested. Otherwise it would just turn into another Custer bash-fest.
