I think they got a tad bit "greedy" with this trailer they had been doing a decent job of staying away from things that were spoiler worthy but this one has things I think they could have avoided putting in a trailer. That said it is a 3-hour movie so I am going to give them benefit of the doubt there is a lot of stuff we haven't seen . Also they have admitted to using scenes in trailers that is not the movies so not everthing we see might be there.
