Do you remember the last time you were talking to someone for more than a couple minutes? Maybe they were explaining something to you, or telling you a story. You might try to remember what they said later - you can’t hear it, but your brain kind of recreates the sensation of having been spoken to even though your ears aren’t receiving those sounds.
That’s what having an inner voice is like (to me, anyway) - it’s remembering a conversation that you never actually had.
I love this movie. It’s probably one of my favorite schlock fantasy movies. The casting was way better than it had any right to be - Hugh Jackman, sure, but Kate Beckinsale? Well, I guess she was fresh off Underworld, so she was still in that headspace. And Richard Roxburgh doing the perfect amount of scene-chewing for the villain… introducing himself properly as Vladislaus Draculea… and the opening scene, shot just like a 1920s Universal monster movie! I legitimately think it’s the closest we’ll ever get to a live action Castlevania. I could go on, but I’ll spare you. Might be time for a rewatch.
