Editing: The beginning of the trailer is very slow to help the audience understand the movie narrative however when it progresses to the ending becomes faster and shows gunshots, expolives nad violence etc. This convention is used in many action movies to create suspense that builds up and concludes making the audience intrigued to watch the movie..

Institutional details: At the end of the trailer it mentions the three main characters, on of which is Laim Neeson which engages the audience to watch the film as he is known as a A class actor. Liam Neemon would attract many of his fans and his name will arouse  the 'word of mouth' as his films have always become sucessful so they would suggest the fiolm is worth watching
