body: Would there be anything illegal if i were to write a script based in the same world as one already existing movie, making reference to some of the characters?
  
  
  For example, if I wrote a script based on The Matrix, but not about Neo and them. But based on a new character who lives in the Matrix and see the events. Would it be alright to include characters like the Agents or Oracle. Would I be able to copy-write the script?
