DP3 trailer views are inflated by the Super Bowl. Whereas J2 is deflated by releasing a teaser earlier in the day.
Anyways, trailer views are irrelevant to box office. Transformers ROTB had some of the highest trailer views of all time.
Joker 2 has a decent shot at outgrossing DP3 domestically IMO. Even with the OS skew, Joker still outgrossed DP2. I think both will see good increases.
