Here's a pretty fair analysis regarding Suicide Squads current box office estimates and where it might land. As multiple sources have already debunked, this film doesn't need anywhere close to $800 million to profit. Also, multiple sources have said this movie was a hit with younger crowds. I've thought about seeing it one more time as well, I may here in a couple weeks when I can get tickets cheaper for it. It also hasn't opened in a few international markets, so there's that also... If this movie had China, assuming it'd make anywhere between $50-$100 million, the worldwide figures would be obviously that much higher. But China deemed the subject matter of the film too inappropriate for their audiences.
