"Gotham" TV series spoilers hint of a veritable riches of villains waging war against Detective Jim Gordon in the pilot episode, as showrunner said they are planning "to open big."

Executive producer Bruno Heller dished out "Gotham" TV series spoilers to TVLine when he said that four villains such as Catwoman, Penguin, The Riddler and Fish Mooney will be shown on the pilot.

The pilot episode is going to be about Penguin and his rise to villainy, as well as his spat with Fish Mooney.

"You have to front-load the pilot with the best that you've got. You have to open big," executive producer Bruno Heller said last Sunday at the Television Critics Association summer press tour.

However, that's not going to be the case every episode since they will be "far more careful with how we roll out the villains and in what way."

The FOX network revealed "Gotham" TV series spoilers in a teaser promo showing the young Bruce Wayne (David Mazouz) looking shaken as he is interviewed by a young Jim Gordon.

"May name's Bruce Wayne," he starts. "A man came out of the shadows ..."

"There is something you can do now," Jim Gordon (Ben McKenzie). "You can be strong."

Earlier, E! News revealed "Gotham" TV series spoilers after uploading a new promo which previewed the tragedy that drew the future Batman and the future Gotham police commissioner closer.

The preview also "gives us another look at several other characters familiar to Batman fans, including Oswald 'Penguin' Cobblepot (Robin Lord Taylor) and Selina Kyle (Carmen Bicondova), aka Catwoman," she said. Carol Kane was cast as the mother of the Penguin.

The website also said that attendees of the San Diego Comic-Con this month will get first look at "Gotham" TV series spoilers when the pilot episode will be shown on July 26.
