In Spain, the film was projected on 2.35:1 screens in the 2.20:1 aspect ratio. But the film was finally projected with black bars on the four sides of the screen. This same situation happened with
Jurassic World (2015) and just before the film started a text appeared on the screen explaining the 2.00:1 aspect ratio fitting on the 2.35:1 screen adding black bars up an down.
Dunkirk (2017) didn't show any explanation before the film.
