Spider-Man: Homecoming, he's too high domestically and internationally. I'm thinking Homecoming will come in around $800 million worldwide, $250 domestically. That's on the low-end in my head, but based on past performance, I feel good with those guesses.
I think his Transformers numbers are correct domestically, but that international number is absurd. Justice League is pretty much right, assuming it's a competent film; the DC universe ceiling seems rather high. Power Rangers is right assuming it's not good. If it is, I'll kick that up to $250 million worldwide at best?
No thoughts on the rest.
Spider-man has the potential to go as high as he predicts, but I'm not sure if it will. Maybe once we get a trailer. Any word on whether the Tony Stark cameo is substantial?
The Beauty and the Beast prediction is absurd. Perhaps the worst one of the entire bunch. Cinderella made $200M domestic and close to $350M international. Unless the film is absolutely terrible, I don't see how it misses at least that mark. If the film is good, I wouldn't be surprised to see it closer to The Jungle Book than Cinderella. Pete's Dragon is inconsequential. Disney is going to break their marketing A-Game to Beauty and the Beast. Perhaps their third biggest/most important film of the year after Star Wars Ep 8 and Guardians of the Galaxy 2.
The Transformers prediction might seem reasonable until you take foreign exchange rates into consideration. Someone over on the BOT forums has been adjusting international grosses of recent movies to account for exchange rate differences between now and then. Dark of the Moon would have made $983M worldwide ($631M overseas) using current rates. Age of Extinction would have made $971M worldwide ($725M overseas) using current rates. China is not going to make up a $175M deficit, especially when Transformers 5 is likely to continue the franchise's drop from Dark of the Moon's high point elsewhere internationally.
The Mummy is way too pessimistic. Ignoring the fact that Tomb of the Dragon Emperor made $400M worldwide, even Dracula Untold (which I think was the supposed to be the original start of the movie monster universe) made $217M. A big budget action film starring Tom Cruise is not going to putter out at less than $30M domestic and $130M worldwide. Since Top Gun, the only Cruise films to make less than what he is predicting for the Mummy domestic were Lions for Lambs and Magnolia.
Jumanji's domestic total is probably too high. I could see it breaking $150M or so. On the other hand, the international take is probably too low. Central Intelligence made $90M overseas, and I think this has more international appeal. ~$300M worldwide might end up in the right ballpark, with a difference domestic/OS split.
Justice League and Power Rangers seem reasonable.
