The industry eviscerated Zalev over this. Financially if pre/post theatrical is covering additional spend beyond production, they are generally getting ahead of an outright write off. It's a pretty bad business move unless you can stop a production a lot earlier.
I won't outright lie and say this movie has blockbuster potential, but it could recoup costs if the public likes it. We also have to acknowledge this is a global movie and most of the reason people really think it is going to fail (controversial statements from its lead) are going to be completely missed by the broader audience, let alone the International one.
I'm not trying to frame this as a total defence. More that I just think 500M on this production seems a lot more likely than 75-100M. Which is a benchmark it would need to undershoot to have been better written off.
