I had originally been quite optimistic, thinking it would perform in the 400million+ at the Box Office, but I am going to cut that down drastically to 60 million domestically in the US and 120 million WW. Reason being, I do not see the hype for it here in the states (anecdotally anyways) and theaters are utilizing their premium screens (IMAX, Dolby, etc) for Guardians of the Galaxy 2 (during its 3rd week, Alien's first) and Pirates of the Caribbean on its first week and going forward (Alien's 2nd and going forward). People I talk to seem confused about it and either do not know what I am talking about or are in the mind of "Oh, is that coming out this year? huh...."...i.e. it does not seem like many people are tracking or following it. I HOPE I am dead wrong but between the lack of enthusiasm from the general public, at least that I have encountered, and the lack of theater confidence in the film, I just don't see it performing well by any standard.
Maybe audiences from everywhere outside the US can make up for its potential lack of performance here. I certainly hope so. I know some people think that it could be a good thing if it does not perform well because it might make Ridley Scott reconsider his direction with the series, but I fear they may just scrap Ridley Scott from control of the series altogether and bring in someone fresh 10 - 15 years from now when they feel its time for another go.
