If JW can open to 200+m weekend BvS may has higher CHANCE to break 200m OW. I can't talk about domestic BO as I am a foreigner. So I am talking about general Asian countries which have a taste for ACTION movies and event films. MOS overseas marketing was pathetic. I have only seen a poster on the scheduled theater a week ago. News paper advertisements were very poor. Only one on the releasing day. If WB goes full on the BvS they can get it work like marvel movies.
because
1. The first time Batman and Superman on same film. (WW and Aquaman are not so popular)
2. The first time Batman and Superman FIGHTING onscreen.
3. The first time Batman in 3D. (Asians still love 3D.

t: Mos was renamed here as SUPERMAN 3D in newspaper advts)
If WB goes full on marketing overseas it can crack 800+ overseas.
