It was a pretty terrifying time for Gotham.
The show’s fifth season would be its last before the Dark Knight Returns, a reboot of the Batman franchise, was shot and released.
That didn’t happen until May 2015, but fans had to wait until the end of that year to see how the show would end.
The season finale of Gotham aired on May 21, 2015, and Gotham was all but assuredly not going to see another season.
We know now, however, that the show’s writers and cast were worried.
The episode was so terrifying, they even started a Kickstarter campaign to raise $5,000 in hopes of getting the show to the end before the end date.
“This is a terrifying episode,” actor Michael Scotto said during the Kickstarter campaign.
“We knew it was going to be scary.
It was the first time we were filming a series finale.
We didn’t even know we were going to shoot that episode until it was over.”
And even though they didn’t know it was coming, the actors did.
“When you watch this episode, you’re like, ‘Oh my god, I need to go back to my apartment and put on a mask,'” Scotto recalled.
“That’s how scared we were.”

The actor said that it was also the most terrifying scene of the entire series, and that it took a lot of thought to bring it together.
“I remember saying to [executive producer] David Fincher, ‘I think we need to do this,’ because it was so difficult,” he recalled.
The actors were still worried at the time, but Finchers assured them that they would get through it.
“He was like, we’ve got a way to do it,” Scotto remembered.
“And that was, like, the end.”
The actor told EW that he and Scotto both got used to the idea of having to hide from the camera, and it was a lot easier to keep the actors calm during scenes like this.
“You have to make them uncomfortable, because the audience’s just going to go, ‘Are you trying to kill me?'”
“So it was great.
The biggest fear for the actors was the fear of what might happen next.”
The episode is a must-see for anyone who loves Gotham.
