Is everyone pretty much thinking the same thing then? ($700,000,000 domestic/$1.4 worldwide) I haven’t seen too many predictions far outside of those numbers.
The Force Awakens opening weekend was $247,966,675 and The Last Jedi opened with $220,009,584, so I would expect The Rise of Skywalker to at least open around $230,000,000.
I’m definitely predicting less than The Last Jedi. I really think a lot of people were turned off by it and don’t feel the need to see final installment.
