It's all up to the word of mouth after the opening, with similar reception to GOTG3, it would have made more than GOTG3. When it comes to hype and anticipation, Quantumania had the edge. Do you actually think Quorum is a good measurement for box office legs?
Avatar 2 made less profit in 2022 than the MCU and that's not including merchandise, Avatar as a franchise wouldn't even be top 5 for Disney, even Cars is bigger.
TASM2 underperformed but was still a $700M profitable movie, DCEU on the other hand is on a record breaking 6-film flop streak, they're not the same at all.
It's not another studio's clip, it's a fake NWH clip that has been posted on Twitter for years and Sony never took it down because it's not from the actual movie, it's fan-made.
Forget Tobey, Keaton's Batman isn't even on Andrew's Spider-Man level, this thing is opening less than what TASM2 opened in 2014 unadjusted for inflation, internationally the difference is even bigger.
