Goyer explained that, despite re-introducing the Joker in the upcoming sequel, the filmmakers want to explore new villains in future films.
He said: "Batman has been published for 70 years. In the first movie, we used Ra's Al Ghul and the Scarecrow, who had not been in the movies before, and had not been in the '60s TV show before.
"There are dozens if not hundreds of other characters that fit that bill. Everyone says it's got to be the Penguin or Catwoman [in the next film]... well I completely disagree."
Along with their appearances in the Adam West TV show, the characters also featured as antagonists in 1992's Batman Returns.
The Dark Knight is released in cinemas on July 25.
