Aurora - Teaser Trailer

The teaser trailer doesn't reveal much about the film at all. We don't know who the
characters are  or who the actors are. The only thing we know is that the people
we see are in trouble from the machines they created.
The clips used in the trailer are from different section of the movie.

Teaser Trailer - Last Vegas

The teaser trailer put great emphasis on the four 'academy award winners', who
are the four main characters of the film. The trailer  offers the audience to see them
as we have never seen before.
Some people could say that this seems like "The Hanover" with older guys,
but there doesn't seem to be a 'hangover', only one huge party for four days with
some of the biggest names in Hollywood.

Teaser Trailer - Anchorman 2 - The Legend Continues

The teaser trailer won't make any sense to someone who hasn't watched the previous movie. For who have seen the first movie, they can assume that the story of each character will stay similar.
The teaser trailer doesn't reveal anything about the story at all.
Additionally, the teaser trailer only shows the main four characters of the movie. The style of the characters continue from the first movie, they are the same. Doesn't contain much text except for the movie name and the release date (2013).
