Both those films are the hard sells and both those films are the ones that have to look out for Snyderman.
I agree. I also feel that even though MOS seemingly has a lot going against it, it also has a few things going for it and maybe even more.
The negative thing for MOS are (all IMO of course) :
1. The taint of Superman Returns and the general unpopularity of Superman from the GA - Though I don't know how they will respond when they see a trailer and see a Superman they never knew existed - in other words completely different from what they have in mind Superman is - basically what they've seen in either Reeve films or SR.
2. The release date - Maybe not the worst but not ideal either, but plenty has been written on that.
3. Zack Snyder - I may hold him in high regard and so does Nolan (and Cameron) but I mostly see negative comments about him coming from the GA. His last 3 films also either underperformed and in the case of Sucker Punch, flopped hard.
On the other hand, MOS has:
1. Christopher Nolan's name - The vast majority of people who disregard the idea of a new Superman movie get interested when they hear he is involved. If TDKR can match or surpass TDK and Nolan's name stays on the story/producer credits, and his name or ´´The creators of The Dark Knight trilogy`` this will benefit MOS, as Zack Snyder's name alone would be alarming.
2. The cast - While no single person is a big box office draw, together they may be the most impressive cast in a superhero movie to date. Plenty of Oscars and Oscar nomination, Golden Globes, Emmys etc between them. Appeals to a wide range of viewers. Who doesn't know Crowe and Costner? Shannon is getting more and more creed. Amy Adams. Lot's of people who know and like Meloni and Schiff from TV etc etc.
3. Action and VFX - I think MOS has the potential to be the most visually stunning movie of its kind. And while we don't yet know the scale of the action (how much destruction in Metropolis, how many - if any - Kryptonians will there be besides Zod and Faora, etc) even though it probably won't quite match the scale of something like Transformers or Avengers it will probably have the same effect on the audience and obviously insane action and great vfx = lot's of $$$ (not in all cases obviously).
The rest will fall on the marketing, which is not WB's strong point but they will have the benefit of having a finished movie on their hands before the real marketing frenzy starts, which means total freedom in selecting footage and no doggy cgi inside it.
And of course, word of mouth. If the movie gets bad buzz as being a typical bad Snyder movie it may be doomed - or the effects heavy action may save it.
And even though it is impossible to predict any numbers before we haven't seen anything, I see no reason why MOS couldn't do at least Iron Man numbers, or even Spider-Man (around 800mil worldwide) if all of the above works like it should. I know a lot of people think it is impossible but I don't think so at all. I think it could easily happen. Then again at this point I think MOS doing less than SR is also a possibility.
The teaser should give this topic some more boost. It will be one of the most important steps in the entire marketing of MOS. Because if the teaser fails to impress/generate interest, Zod help MOS.
