Behind the scenes facts
The struggle of a tall person is not always as obvious as it appears to the audience at home. This pair likely appeared to be about the same height as the audience at home. A passer-by, however, on the street or the internet knows the truth.
We’re not sure why the guy on the left felt he needed to make such a concession. Perhaps he didn’t want to appear above his co-star, or perhaps he was instructed that if he wanted to be in the shot, he would have to lower himself? Hopefully, it was a quick scene.
