If they were smart they would let Lilo & Stitch have more room to breath and push Elio out even more. HTTYD will be sucking up money for longer than a week.
I'm not sure where they could push
Elio to. The week after the new date isn't crowded, but would give it just 5 days to make bank before
Jurassic World Rebirth opens, then
Superman opens the weekend after that. Pushing it all the way to the 18th of July puts it just one week before
Fantastic Four: First Steps, and Disney won't put two giant movies on top of each other like that. (It's also the same day as the latest
Smurfs movie.) The first weekend of August would put it directly against
The Bad Guys 2, and the weekend after that is already booked by Disney with
Freakier Friday.
After that, the only month "open" for
Elio would be September, since
Tron: Ares is getting the October slot,
Zootopia 2 November/Thanksgiving, and
Avatar: Fire and Ash December/Christmas. And as well as
The Wild Robot went over with audiences and critics in a late September slot, it didn't do the kind of numbers
Elio has to do in order not to be perceived as a flop.
