First off, I am so glad that this site exists. I’ve been searching for this trailer for months, and I cannot seem to find it.
Basically, all I can remember is my memory of a trailer for a movie or maybe for a music album… I don’t think it was a video game… and the trailer featured Mozart’s “Lacrimosa” to show a particularly dramatic scene. It was a piece of English media. Here’s a clip of the song: https://www.youtube.com/watch?v=k1-TrAvp_xs. My memory is of around 2:05 of the song; that’s the part that was in the trailer. I think this was relatively recent, probably within the last decade or a bit over. Hope you can help! Thank you so much!
