There is almost no promotion for the movie here in Europe. Hardly anyone knows about it. And that includes the regular Disney/Pixar/nerdy crowds.
Makes me think why. It is set in space, right, and the rest in the US? I know with the current political climate the US is not very popular over here, but I can't imagine it is so bad that Disney would stop promoting a movie set in the US. It seems unlikely, but I can't think of any reason why Disney would not promote this movie.
In my own town, there are only 2 viewings per day, both a dubbed Dutch version. The original version in English was only shown the first few days.
I got an email from my movie theater and they give a short list of family movies to watch this summer. Several Dutch movies, How to Tame your Dragon and Lilo & Stitch. No mention of Elio.
I am a bit curious, but not enough for the high prices movie theaters charge nowadays. Downside, I do not have
Disney+ anymore, so if I want to see it... I do have to go to the theatre.
