It did always strike me as funny that Cronenberg had a movie about "what if TV was evil and made people murderous and the studio execs had to pay", and a movie about "what if video games were evil and made people murderous and their creators had to pay", but never a movie about "what if movies were evil and made people murderous and film directors had to pay". Obvious bias aside I wonder if it would work as a story - movies don't seem as hypnotic in the public consciousness, I believe.
