An opening sequence is used to give the audience a gist of what the film is about but not giving the whole story away, it sets the tone for the rest of the film, showing you what kind of genre or theme the film is going to have, also the main actors are usually shown.
Cinematography-
Shallow focus is used when the knife is taken out of the drawer, it focuses on the knife, creating suspense, the audience start to question the antagonists reasons/purpose, shallow focus is very conventional of a thriller, it is used to show who/what you should be looking at to take your mind off other things in the background, possibly to create a jump scare or help you keep up with the story, or even just to create tension/suspense , it is also to help you realise what the main thing in the scene is, the fact it is a knife creates shock as the audience know that this is not good so are in suspense wondering what will happen next, engaging them, the audience create a relationship with the antagonist, they begin to fear him due to him having possession of such a lethal weapon and they know he is going to do something serious with the weapon as it has been focused on. Shallow focus is conventional to the thriller genre, it is constantly used to create suspense and surprise, and sometimes even shock, the use of this engages the audience and helps them realise that something is going to happen with whatever is focused on, creating a tense atmosphere within the audience and engaging them into watching on to see what happens.
Editing-
Timing of shots is used to speed up the scene where the murderer 'michael' is trying to run away after stabbing his sister, this shows he is trying to quickly get away before anyone sees him or notices she has been killed, this creates suspense as the audience wonder whether he will escape in time or not and also a hint of suprise that the antagonist is rushing as he seemed calm and composed before murdering the woman and it is unconventional to see the killer in a rush, the audience question the antagonist as it is unusual for them to run, therefore they wonder what is happening.
Conventions-
The scary/eerie music used in the build up to the murder creates an enigma aswell as suspense, we wonder what is going to happen and why the antagonist would have these intentions and how the victim and the antagonist know each other (or if they do not), all these questions help build the tension along with the music, letting us know that something is about to happen but doesnt tell us when. This type of music is used constantly in thriller movies to put viewers on the edge of their seats, the music puts the viewers on the edge of their seats, they know something is about to happen but they don't know what or when.
Sound-
Non-diegetic sound is used after Michael kills his sister, it is used to create a tense atmosphere among the viewers and let us know what kind of mood/tone the movie is at the time, the sound is parrelel to the images we are being shown. This is typical of a thriller film as non-diegetic sound is always used to create an atmosphere in sounds, the audience are in suspense as to what may happen, they want to watch on to see what is going to happen to the antagonist, the music is also used to create shock and emphasise what Michael has done, also sound is used to create surprise when it is revealed that Michael is a child, the audience were not expecting this and are surprised as well as shocked, the audience create a relationship with michael, they fear him as they wonder what makes a little boy murder someone, the audience are cautious of his character yet question whether what they have seen has actually happened. non diegetic sound is conventional to the thriller genre, it is used to create shock, suspense, surprise and even enigma, it is a key part of thriller films and without it these shock, surprise, suspense and enigma are very difficult to create within the audience are very difficult to make, this makes it extremely difficult to engage the audience.
Character-
The hidden identity of the killer because he is wearing a clown mask creates a sense of enigma and suspense, we wonder what this crazed antagonist looks like and wonder why he would want to do such a thing, also it is much more of a surprise when we find out who the antagonist is. Hidden identities are typical of thriller films as the audience are always in suspense when they know little/nothing about a character, especially a main character like the antagonist, this makes it easier to create surprise/shock when the identity of the character is revealed. The fact that the antagonist has a mask creates an enigma, the audience know little about the antagonist, this helps create a relationship between the antagonist and audience as they fear him as they know very little about him.
Narrative-
Due to it being on Halloween night, hidden identities are not out of the ordinary as everyone is dressed up, there are elements of enigma throughout as the killer is completely anonymous due to the POV camera shot plus he puts on a mask, this enigma creates suspense and a much bigger shock when we find out who the killer is. This is typical in a thriller film, Halloween nights are known for being a night where lots of people are scared, this is why it is so commonly used in thrillers, the audience have already associated halloween with murder and hidden identitys so the movie plays up to it, allowing it to be much more realistic in a sense .
The target audience are in suspense throughout the whole scene, they are also shocked when the murder victim says the name of the killer, implying she knows him, which creates enigma, we wonder what his motive is and how he knows her. We feel fear towards the antagonist, at no point do we know that he is a child, there are no indications of this, whenever an adult character is in the scene he always looks around the same height, this is because he is always put on a 'platform'/higher position, for example, when he walks into his sisters room she is sitting down whereas he is standing up, then when he walks outside and his parents get out the car he is on a pathway which is higher than the road they are on. We feel sympathy towards the sister as she was clearly not expecting what was about to happen, she knew the killer and had no chance to react and escape as she was not expecting to be killed by Michael.
The audience are shown many conventions during this opening scene, a typical household, a place you would see in everyday life, making the scene feel a lot more real and shocking, but the house looks very isolated, a conventional part of thrillers, this makes the audience realise that no one will be able to intervene in what the killer is about to do, also the victim is a typical helpless female victim, this is again, a convention of thrillers, the males tend to be the antagonist or protagonist and the females the victim that needs help, also the shots focus on the iconography like the knife and mask, these two are conventional to thrillers, the mask creates an enigma as to who the antagonist is and the knife shows you the true intentions of the antagonist, camera shots like POV are used a lot in thrillers, it allows us to feel like we are really in the scene and we cannot see the antagonist, only what they are seeing, it creates an enigma as to whats around the killer as we cannot fully see the setting. All of these show the audience some typical conventions in thriller movies.
This research has allowed me to realise what kind of conventions i should put in my film, i know that i should use a setting that people see in everyday life, this makes the scene much more shocking , also it should be in an isolated area to make the audience feel suspense as to whether the victim will be able to survive alone against the antagonist, i should use eerie music that is not heard during everyday life, making the audience nervous as to what this means for the victim and parallel sounds like the clock chiming, this is a recognisable sound and is a symbol of the victims time running out. I think the idea of a child antagonist is unique and exciting/shocking, this is unique compared to other thrillers and think this could possibly be a good idea for my thriller, but the main reason it is so shocking/disturbing in comparison to a adult antagonist is because children are seen as helpless and innocent, the fact that it is not revealed that he is a child until the end of the scene is why it is so shocking, i may use the idea of not revealing the killer until the end as well, it creates a lot more shock than knowing who the murderer is before the killing
