Project Almanac film trailer analysis

The first 30 seconds of the trailer show a boy re-watching a video from when he was younger when he discovers something strange. He seems his older self in the video which is impossible. This entices the audience to the trailer because they will obviously want to find out how such a thing is possible. The non- diegetic music at this point is quite upbeat and happy rather than mysterious. This could show the audience that what they are about to discover is a good thing rather than a bad. It is clear that throughout the trailer it is supposed to look like it is self filmed. This can be made obvious by the way the characters occasionally look directly at the camera. The fact it is self filmed will make the audience feel more involved with the film as it seems like they are actually experiencing what they are experiencing. We see various close ups of some sort of machine the boy and his friends have found. When they work out its a time travelling machine that his dad was working on we can see that they all cannot believe it. They then decide they should make it because it is made clear that they have already made it if he was in his baby video.
For over half of the trailer we can see that they are taking advantage of being able to time travel by winning the lottery for example. To the audience and to them it seems like harmless fun. The non- diegetic music at this point is upbeat which could again make the audience believe that it it simply just a bit of fun. However, the music suddenly comes to a stop and the music changes to quite fast paced and low. This is when it becomes clear that what they are doing is having an effect on everyone else. We see various close ups of them looking carefully at newspaper articles of disasters that have happened because of what they have been doing. One particular over the shoulder shot shows the boy reading the newspaper and we can see the headline 'Plane Crash 77 killed'. This therefore allows the audience to fully understand the extent to what they have caused. For the rest of the trailer we see a mixture of shots from the bad things that are happening now and the good things that happened whilst they were time travelling. The effectiveness of this is that it allows the audience to realise that this must be a hard decision for them to make because it would mean reversing all the good stuff that has happened even if it risks their own lives.
