According to F. Gary Gay’s comments to The Hollywood Reporter, this meant hotels weren’t used to having that many guests and people weren’t used to having filming done down their street.
Such was not the case in Cuba, where filming scenes like the opening of The Fate of the Furious were in violation of U.S. law previously.
Filming a movie on location always has major logistics requirements but so many places do this all the time that everybody knows how to handle it.
Even in Los Angeles, where such things are more common, you’ll get fans on a film set trying to get a glimpse of their favorite stars, but one can only imagine how much worse the whole thing would have been in Cuba.
