During a media conference call, executive producer and writer of Gotham Bruno Heller confirmed that there's no limit to the amount of villains which could be explored throughout the series.
"The simple answer is: No. We're ready to go with any of them" he said.
"We haven't excluded anyone from the mix potentially, but generally what we're looking at is characters where there is some drama or a story behind how they got to be the way they are".
"We're looking for characters who live in the real world of Gotham as opposed to the even more super real world of Metropolis if you like. It's not about super powers, it's about super will, if you like. We veer towards those characters who are interesting as people, rather than interesting for their particular power or their particular gimmick or their costume."
Hinting that though we may not see every favourite on screen because of the difficulties in adapting them, he noted there's always a chance for any bad guy to turn up.
"There are certainly characters that would be very difficult to put on the screen. That crocodile guy [Killer Croc] is a tough one - although we may go there" he explained.
Already confirmed for the Gotham lineup are Selina Kyle, Edward Nygma and Oswald Cobblepot, as well as Poison Ivy and Mr Freeze.
Gotham premieres on FOX Monday, September 22 at 9pm and on Channel 5 in the UK next month.
