You’ve probably seen the posters. Maybe you were scrolling through a fandom wiki or a sketchy TikTok "leak" and saw a high-definition image of Mark Wahlberg in a tactical Batsuit or Adam Driver sporting the jagged visor of the Arkham Knight. It looks real. The credits look official. People in the comments are arguing about the "release date."
But here’s the reality check: there is no cast of batman arkham knight film because there is no Batman: Arkham Knight movie.
At least, not a real one produced by Warner Bros. What you’re seeing is the massive, slightly obsessive world of "fanon"—fan-made fiction that has become so detailed it consistently tricks Google's algorithms and confuses casual fans. It’s a rabbit hole of "what ifs" that has taken on a life of its own. Honestly, it’s kinda impressive how deep the lore goes.
The Viral Myth of the 2021 Live-Action Movie
If you search for the cast of batman arkham knight film, you’ll likely stumble upon a Fanon Wiki page that insists a film was released in 2021. It lists a wild, star-studded roster that feels like a fever dream. According to these fan-made entries, the movie stars:
- Mark Wahlberg as Tim Drake (who apparently becomes the new Batman).
- Adam Driver as Jason Todd / The Arkham Knight.
- John Noble reprising his role as Scarecrow (this is the only part that actually makes sense).
- Willem Dafoe as the Joker (a hallucination, obviously).
- Oscar Isaac as Nightwing.
It sounds like a blockbuster, right? But it's totally fake. This "film" exists only in the imagination of creators who write elaborate scripts, design posters, and even "cast" their favorite actors in a digital sandbox. Because these wikis use the same formatting as legitimate movie databases, they often get pulled into search results as if they’re factual history.

The Real Cast: The Voices Behind the Game
While the live-action movie is a ghost, the actual project—the 2015 video game Batman: Arkham Knight—features one of the most legendary casts in the history of the franchise. If you’re looking for the people who actually brought these characters to life, you’re looking at a masterclass in voice acting.
Kevin Conroy: The Definitive Batman
For most of us, Kevin Conroy is Batman. This game was his final performance in the main Arkham trilogy before his passing in 2022. In Arkham Knight, Conroy plays a weary, pushed-to-the-limit Bruce Wayne. He also voiced Hush (Thomas Elliot) in the game, showcasing a range that many people missed on their first playthrough.
Mark Hamill: The Ghost in the Machine
The Joker is technically dead when the game starts, but Mark Hamill returns as a persistent hallucination. It’s some of his best work. He’s not just a villain; he’s a heckler. Hamill famously said he was retiring from the character after Arkham City, but the script for Knight was apparently too good to pass up.
Troy Baker: The Man of a Thousand Voices
Troy Baker is the MVP here. He doesn't just play the Arkham Knight; he also voices Two-Face. He’s basically arguing with himself in some scenes. In previous games, he even voiced Robin and stepped in for Hamill as the Joker in Arkham Origins. If you hear a male character in a video game and you aren't sure who it is, there's a 50% chance it's Troy Baker.

John Noble: The Sound of Fear
This is where the fanon and reality overlap. John Noble (Fringe, Lord of the Rings) voiced Scarecrow. His voice is deep, gravelly, and genuinely unsettling. He replaced Dino Andrade from the first game, shifting the character from a "crazy scientist" to a "philosophical terrorist."
Why the Confusion Still Happens in 2026
We’re living in an era where AI-generated trailers are everywhere. You’ve seen them on YouTube: "BATMAN: ARKHAM KNIGHT (2025) - First Trailer | Jensen Ackles, Robert Pattinson." These videos use deepfake technology and clips from other movies to create a "proof of concept" that looks terrifyingly real.
When you combine these high-quality fake trailers with the "Fanon Wikis" mentioned earlier, it's easy to see why people get confused. People want this movie. The Arkham trilogy is widely considered the best adaptation of Batman outside of the comics, so the hunger for a cinematic version is constant.
What About an Actual Movie?
Is there a chance for a real film? Sorta.

Warner Bros. has a history of making animated films based on the Arkham universe. Batman: Assault on Arkham (2014) is set in the same world as the games, though it’s more of a Suicide Squad story. There have been rumors for years about a live-action "Arkham" project, but with James Gunn’s new DC Universe (DCU) taking center stage, a direct adaptation of the game seems unlikely.
The DCU is focusing on The Brave and the Bold, while Matt Reeves is sticking to his The Batman universe. An Arkham Knight film would just muddy the waters too much for the general public.
Key Takeaways for Fans
If you're trying to track down the cast of batman arkham knight film, remember these points:
- Check the Source: If the website says "Fanon" or "Idea Wiki," it's 100% fictional.
- Voice Cast is King: The 2015 game features Jonathan Banks (Breaking Bad) as Commissioner Gordon and Ashley Greene (Twilight) as Barbara Gordon. That's the closest we've ever come to a Hollywood-level live-action cast.
- Watch the Animated Spin-offs: If you want more Arkham lore, Assault on Arkham is your best bet, even if the continuity is a bit messy.
- Ignore the "2021 Release" Rumors: There was no secret movie released during the pandemic.
Instead of looking for a movie that doesn't exist, I'd suggest revisiting the game with a focus on the performances. Notice how Matthew Mercer takes over for Troy Baker as Robin (Tim Drake) in this installment so Troy could focus on the Knight. Pay attention to the subtle way Kevin Conroy's voice changes when he's talking to the Joker versus Alfred. That's the real "film" experience.
To get the most out of the Arkham experience today, you should look into the "Return to Arkham" collections which upscale the original performances, or check out the behind-the-scenes "Voices of Arkham" featurettes on YouTube. They show the actors in the booth, which is honestly more interesting than any fan-made movie poster.
