All I know is that several years ago, I recall reading an official article off a site where a motion-capture actor was being interviewed, and he said he was hired by Konami for his latest project which was doing work for a next-gen 3D Castlevania game in Japan, that they hired him to do several scenes. But then the project was canceled & he moved on to other things (and no, it wasn’t Lords of Shadow)
That right there tells me that their was some effort & resources put into it than a simple teaser trailer. If someone can find that article that’d be great, but this is going back at least a decade so good luck. I do distinctly remember reading it though, so so I’m not just pulling this out of my ass
