11 Mind-Blowing Facts You Didn't Know About Batman: Arkham

11. It Took THREE YEARS For Fans To Find Arkham City's Last Easter Egg

Batman Arkham City Calendar Man

After Rocksteady surprised everyone with the revelation that Arkham Asylum was hiding a secret room all along - one that teased the Arkham City sequel, no less - fans were prepared for the follow-up. They chronicled Easter eggs, riddles and story revelations that could have a part to play in an inevitable sequel, and when the Scarecrow lab boat was revealed just after release, everyone thought that was that.

Only, it wasn't.

Fans scoured the game far and wide searching for something - anything - that they could get their hands on. There were already an abundance of nods and winks to what would later become Arkham Knight, but Rocksteady maintained there were still things in the game that fans were yet to find.

Eventually, a full three years after Arkham City released, the final Easter egg was revealed. It was tied to Calendar Man all along, because even though fans had visited him on specific dates to get new dialogue, they hadn't visited him on Rocksteady's birthday. Doing so sparked dialogue that hinted at the events of Arkham Knight, the climax of Rocksteady's trilogy, and of the studio's development itself.

Content Producer/Presenter

WhatCulture's very own resident movie guy, Ewan has been working in the content creation biz for over 10 years now, having started as a freelance contributor to WhatCulture Gaming all the way back in 2015. After graduating with a First-Class Honours in History from Northumbria University in 2017 (where he won a prize for a totally killer dissertation on the Watergate years), Ewan took on the role of Comics Editor at WhatCulture and quickly developed WhatCulture Comics into one of the biggest superhero-focused channels on YouTube. He followed this with a brief hiatus at Screen Rant in 2021, where he worked across the Gaming and Film sections as a writer and editor, before returning to WhatCulture as a Senior Content Producer / Presenter in 2023. He started his own podcast, We Love Dad Movies, in 2022, and has contributed several written pieces to the Eisner-nominated comics website Shelfdust as well. In his current role, Ewan incorporates his love of cinema, comic books, and history into written pieces and video essays for WhatCulture's Film & TV channel, as well as WhatCulture Gaming and WhatCulture Horror, with a particular focus on nineties-era Dad Movies, old school Westerns, and Golden Age Hollywood Noir. John Carpenter is his fave, and he thinks Batman Beyond should never have been cancelled. If that's your vibe, you'll probably like his stuff.
