Since the scene is pretty dialogue-centric and grounded in reality, I want there to be little audio outside of the discussion. I think having too much non-diegetic audio would take the watcher away from what is happening, so the majority of the audio will be able to be heard by the characters and any music I play in the opening must have a source.
Vomit (I know, ew)
First and foremost, one thing that's been plaguing my mind is how the vomit sound effect is going to work. Nothing will be shown and we'll only hear the sound from outside the bathroom door, but I really want it to sound good since it's the most climactic scene in the introduction. I have a couple options:Option 1: Find a fake sound effect online. This would be really easy if I can find a good effect. This also unfortunately involves sifting through tons of vomit sounds, and I have to find one that works spatially for exactly what the shot shows, so that might be difficult.
Option 2: Foley! This one's a bit less easy but will create a more convincing sound since it actually exists in the space. I could use something like oatmeal, but it would feel wasteful, and I can't think of something I could flush down the toilet that's not a food, but this one's a "maybe".
Option 3: Change up the scene so I don't need to make an effect. Maybe Marina put her hands under her mouth to be quieter. This not only removes the need for super realistic sound effect, but it also reinforces what I want to do with the opening, which is create sympathy for Marina and separate her from the disorder that hurts her. Not hearing the visceral sounds would have less of a gross-out effect. However, if it's not heard, it might be unclear to the audience what is happening, so I need to make sure that it is evident.
Music
I still don't know if I even want music in the opening, so I'll see what post-production me thinks, but for now I have a list of songs I think I could use for either the end portion or the beginning when she's talking with Daria. As you might've figured, I want Marina to have a bit of a 60s vibe, so most of the songs here will either be from that time or have that energy.
