8 Details You Didn't Know About 1917
5. The Tree
The movie begins with Lance Corporal Schofield sitting against a tree, with his friend Blake lying on the grass beside him. After the two-hour runtime, the story goes full circle and Schofield ends up sitting against another tree, in the exact position as he started at the beginning of the movie.
This could symbolize the ending of a journey, but at the same time it's open for interpretation and it could as well mean that nothing really changed. Schofield did what he had to and Blake died for it, but everything is still the same. There is still a war, and everyone who has started a Fallout game knows that War never changes. This feeling of hopelessness and despair is strengthened by Benedict Cumberbatch's character who says that there will be new orders to charge coming in any day.
Did that last paragraph ruin your mood? According to 1917's IMDb page, rumors from the set claim that the crew didn't know that the tree was going to be used for the last scene, so they used it in lack of a toilet.
