For this trailer I handled sound design and music, but nothing about it was loud or aggressive. The film has a slow, eerie mood, so the sound needed to feel psychological, not explosive. No big booms, no huge hits. Just tension that creeps in and makes you uncomfortable without knowing why.
A lot of the sounds in this trailer are not what they seem. If you think you hear a metal chain, there’s a good chance it’s actually a tiny glass click from Serum layered on top of a wooden toy rolling on the table. If something sounds like fire, it might just be magnetic tape being twisted by hand. I have real samples of all those things, but sometimes using the “wrong” source gives the sound a strange, deceptive quality. Your brain recognizes the idea of the sound, but something feels off, and that’s exactly what worked here.
The whole point was subtle unease, built from small tricks the audience never notices but definitely feels.
