I remember seeing a move trailer several years ago, but I can’t remember exactly when it was playing. The trailer (I THINK, because all this info is from memory) was a man talking over a speaker to someone who appeared to be in some sort of puzzle game/maze/weird environment with strange colors and a very bizarre esthetic. I remember seeing a lot of bright colors and a guy with white hair-keep in mind this was a while ago and my memory of it isnt complete) I believe it was a foreign film but if I remember correctly, they were playing the trailer at some major american movie theaters. It very much reminded me of A Clockwork Orange/Dark side of the moon type visual experience. I think it was within the last 10 years but I could be wrong. I have been trying to think of the name, which is possibly just one word, and it is driving me crazy! Please help!
Might be a long shot but parts of your description remind me of Beyond the Black Rainbow.
Bingo! Thanks a lot.
Glad to help.
