Two main characters were a girl/woman and a man who may have been masked and named Valentine/Valentino. It’s been a long time since I saw it but I would guess mid to late 2000s was when. There were flying eyeballs and something to do with chalk writing on a brick wall. I’m getting a Phantom of the Opera feeling from my memory of the dynamic between the two characters but I may be off. It’s was very bizarre all through out. English and in color.
“V for Vendetta” (2005)?
