Russo Brothers

In September 2018, the Russo Brothers posted a picture on social media of the Avengers: Endgame set, with the caption “Look Hard.” This led many to speculate and believe the title of this film was hidden (which at that time hadn’t yet been revealed) somewhere inside the photo. In fact, the film's subtitle, “Endgame,” can be made out by the shapes and layout of the objects in the image.
