Thriller Conventions:
1. Our thriller does have crime as a core theme. It is implied that 2 people are murdered in our thriller. This furthers convention number one in the list above.
2. Our film does not have a complex narrative structure, I for one found it very easy to follow. However it must be noted that this is just the opening of the thriller, and if we were to make a whole film, it'd probably get more complex as time goes on.
3. There is a main problem in our thriller, the problem being there is a psycho murdering people. A lesser problem is that there seems to be no motive, and that would be a central theme to find out who this guy is and bring him down. This furthers convention number 3 in the list.
4. The protagonist in our film is dis-empowered, however whether she would continue being the protagonist, as its implied she's murdered is unclear. Also the way in which she is dis-empowered is quite straight forward, and she appears a bit gullible. This sticks with, and goes against (half and half) convention 4 on the list.
5. In our film, a murder takes place in a park. A park is a pretty normal setting, however a murder is not a normal sight. This furthers Convention 5 on the list.
6. Our film is too short to really develop any sort of character identity.
7-8. Not explored in our film.
9. The protagonist's main flaw is that she is overly gullible, and the antagonist exploits this by making her go to her supposed doom, by using the note. This furthers convention number 9 on the list.
10. The titles are in red, which is a representation of the antagonists unexplained blood lust. They also make the film become interrupted as they only appear when the screen goes black. This represents the antagonists love of the dark and of death and the fact he only thinks about himself. This furthers convention number 10 on the list.
11. Right at the end of the film, the protagonist of the film is trapped and it is assumed she is either killed or in grave danger. This furthers convention number 11 on the list.
12. In the beginning the park is vast and empty, this could represent how alone the protagonist is in her plight and the enormity of the situation about to arise. The antagonist on the other hand is dressed in all in black and is expressionless to reflect the remorseless killer she's going to have to go up against. Also the antagonist has dark patches under his eyes, like massive bags to show perhaps maybe he's not been sleeping and is not of sound mind. This means the protagonist has to go up against not only a killer, but a mad man.
In the 2nd part of the film, the mise-en-scene becomes very dark to reflect the evil that dwells in this place and how much danger the antagonist is actually in. The antagonist looks shocked and screams at the end, showing how scared she is, and how hard she's finding it to cope with the situation at hand. This furthers convention 12 on the list above.
Our film is similar to the the the intro of Halloween where the girl is walking and finds herself in a dark scary place. As you can see they both take place in a dark corridor type place. Admittedly in backstabber it is darker, but the concept is the same, alone, trapped in the dark walking along a corridor.
