Our film "Surveillance" incorporates several conventions of thriller films, including:
1) Using low key lighting to make scenes seem more dramatic and mysterious, similar to how it is used in typical thrillers.
2) Having a male antagonist/killer and a female protagonist who develops strength, mirroring common thriller tropes.
3) Incorporating suspenseful non-diegetic music to heighten tension during uncertain scenes, like normal thrillers do.
4) Including aspects of violence like two killings, one shown and one implied, to make the film scary and keep audiences engaged in the mystery.
