Sounds pretty high to me. Total movie budget is 200M. So earning 5% back with only domestic previews, not bad. Edit: i assumed it's 9M after the theatres get their cut btw.

Looking at the budget i wonder if actually canning it was ever on the table.

Apparently it's a pretty decent superhero flick, but also the lead character's actor was recently revealed to have been in a relationship with a 12 year old when he was in his 20s, and Warner Brothers still went ahead with putting his face on all the posters, featuring him in the marketing, and inviting him to the red carpet premiere.

So, yeah, personally not planning to spend any money on it myself.
