The first part of the trailer is the production company logo, this shows that they want people to know who made the film before they watch the trailer. The company was Universal, this is not a small company, they are in fact a huge company and have many other parts to their company such as gaming. Since the company is so large straight away the audience who know of them are expecting a good trailer and then a good film.
Once onto the main bit of the trailer it starts with transitions to add effect and then there is the sound of a man asking questions, with the visual effects of the transitions and the series of questions asked to the man in the picture when each transition has finished makes us feel as though there is a puzzle to the film and the transition represents everything attempting to fit together, in all of the transitions the ending image has a black strip down a part of it, this could have a meaning of perhaps there is always a piece of the puzzle missing. When they have finished there is a piece of text fitting to the trailer and then the visual effects are back to normal and the man is the main subject of the trailer, this could mean that there is a sudden realistion of the truth and the image then goes to being a full screen meaning that the gap has been filled and there is not so much of a mystery and character knows what he must do and then there is alot more fast paced action scenes happening telling us that the sub-genre of the film is action but the mystery of the character finding the truth is what makes the film a thriller and this can be clearly seen from the trailer which means that it is a success on letting us know what the film is about.
The male character is shown alot throughout the trailer and is shown injured at the start, and the voice of the man asking him questions made it seem as though he was trying to help him like he was a doctor and then you see an injection, soon after that he was being asked to do things which meant that clearly it worked, then soon after that there was a burst of action meaning that something went wrong and it gives you insight on how the character came to getting injured in the first place because of all the dangerous things that were happening.
The release date is shown at the end of the trailer with a small bit of information linking to the website of the company, this means that the company are focused on promoting the film and they have given a way of learning more about the film by showing them the website where they will have a whole site only for the film and on that site they will have ways of buying the film and release dates and other additional information.
