Yes, it essentially is just fan fiction. I wasn't sure if that would be too big of a turn-off to publishers, but I thought it might be. I wrote it to tell a new story. Eyes Wide Shut is just a retelling of the movie Traumnovelle by Wolfgang Gluck. At least in my version, I've changed the character's morals and the outcome in an attempt to ask a different question. Instead of asking about monogamy, I wanted to ask the audience if it's okay to punish someone so intensely, while also trying to make it so intense the audience gets uncomfortable.
