Moving images and text:

They use emotional moments to emphasise the feelings of sadness in the movie, in specific the tone in which the characters are speaking very peacefully and in down to earth manner.
The music also emphasises the same emotions as the music connotes something sad and tragic occurred, this was also happening whilst the explosions and battles was continuing.
There was various movie companies featured in the beginning of the trailer, this is so the audience are then comfortable, this assures them that they are watching the right movie.
The text brought up doesn't feature much of the stars starring in the film, however they feature more of the directors and producers and their previous work in the movie industry. This suggests that the producers&director are crucial to the movie and are likely to grab the public's attention.
The voice over man is prevented in the trailer and they have used a character in the movie instead.
The release date and title is also featured.
The iconography in the trailer is explosions so this suggests that it is Action, and the spaceships and different planets featured is suggestive that it is a sci-fi and finally the emotions featured in the movie means that it is also a drama.

The shot of the central image is a low long shot and they have selected this shot because it captures the whole characters outfit but more importantly it makes the character look superior, heroic and most importantly powerful.
From looking at the sign in between the title you could immediately tell that this is a comic movie and features a superhero which means that it is more likely to be a sci-fi.
