Analysis of the film Back to the future

Opening scene of Back to the future

What genre indicators are there? 
We can infer that the genre of the film is science fiction. This is because the main character is surrounded by clocks in the first scene. The clocks indicate time, this could link to something happening in the future as the clue is in the name but also the clocks are set 25 minutes late. There is also another indication that it is a science fiction because in docs house there are many contraptions that nobody has ever seen before.
What question are the audience encouraged to ask themselves about the narrative/main character?
There are many questions that the audience may be thinking such as why did the doc set the clocks 25 minutes late? who is Marty? what is Marty' relation towards the doc? We hope all these question can be answered whilst the film continues. also another question that could be asked is what are all those inventions for? what do they do?
What do we find out?
We find out that there are two main characters, Marty and Doc. At the start of the first scene we only see Marty's feet but then the camera slowly makes its way out to showing his face. We can see that Marty is a teenager and that he still goes to school, as when the Doc called he said he was going to be ate for school. Even though we do not see the Doc we can infer that he is another main character because Marty was at his house with all his invention so this must tell us that most of the film will be based around them two. We can also tell that Marty is quite mischievous as he turns on the amp and the speaker to as high as they can go, when he plays the guitar it blows the speaker up because he turned it up too high.
How is the music ambient sound used and what mood does it create? 
There was not much music or sound in the opening scene. the only things we hear are clocks ticking, the radio and the television. This does not create any sort of mood it just sounds like a load of noise all put together.
What camera shots stand out for you and what is there effect or appeal?
there were any close ups used during this scene. There were close ups of the TV, many of the clocks, Marty's feet and skateboard and some more. There was the occasional medium shot, this was when they first showed Marty, and when he played the guitar and blew the speaker up. All in all the opening scene of back to the future did not give much away and leaves you guessing with whats going to happen.
