"Gotham" TV series spoilers reveal a tragedy that looms over Bruce Wayne and Detective Jim Gordon, as "Batman" writer Alan Brennet vows on boycotting the show over his royalty claims.

Tierney Bricker revealed "Gotham" TV series spoilers on E! Online when it uploaded a new promo that 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.

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.

Meanwhile, Alan Brennert, author of the Detective Comics #500 story "To Kill a Legend," took to his Facebook to complain that he wasn't given his just due in terms of royalty, which is why is boycotting "Gotham" TV series.

According to the "Batman" writer, whose "To Kill a Legend" was voted a fan favorite, his character Barbara Kean, the fiancée of Jim Gordon, was used in the TV show without properly giving him royalties.

When he told a DC executive that he's entitled to equity for Barbara Kean, his proposal was dismissed because "she was derivative of her daughter Barbara (Batgirl) Gordon and equity 'is not generally granted' in derivative characters like wives, husbands, daughters, sons, etc. of existing characters."

"Now, let me be clear: I've since learned that the amount of money involved here can be as little as $45 an episode for a full equity character. So clearly I'm not in this for the money, but the principle," "Batman" writer Alan Brennert added of the issue on "Gotham" TV series boycott.

The novelist suspected that DC thinks the equity is low enough to discourage somebody like him to hire an attorney. "They also count on the fact that their freelancers depend on DC for work and thus will not publicly call them out," he wrote on his Facebook.
