I wonder if this film will be trailered to death like Avengers was. If you watched the Graham Norton show, they had virtually half the Hulk-buster fight clip on; and that is one of the biggest (best?) set-pieces of the film!
I tend to think it won't be. For some reason, the Avengers seems to have been over the top on the marketing, they didn’t really do it as much for the first one. For some reason, I wonder if it’s because they were worried about audience fatigue for this one, that they decided to really go to town on the clips, interviews etc?
One reason I don’t think this will go down that route is the way they’ve marketed it so far, as we know JJ Abrahams is notorious for secrecy, is that the teaser and the second teaser both essentially showed the same scenes just from slightly different perspectives. And they still haven’t given anything away character wise. No sense of story, no lighstaber fights etc. We’ve basically seen Rey, Finn, Poe and the Falcon from different angles. That’s all.
So I don’t think they’ll suddenly hammer it before it comes out. It’s Star Wars, it doesn’t need it.
