In the Batman vs Superman movie Lex talks about how in his father's study there's this painting that should be flipped upside down because demons come from the sky.
Best image I could find of it, before you even tell me it's definitely not "Fall of the Rebel Angels" from Paradise Lost but very similar.
It might've been made for the movie but if anybody can get a clear image of it that'd be great.
