TT Games released LEGO Batman: Legacy of the Dark Knight on May 22, 2026, and if you thought the studio was going to play it straight, think again. The game is absolutely loaded with Easter eggs, hidden gags, and pop culture references stuffed into every corner of its bricky Gotham City. IGN's executive editor Matt Purslow catalogued 48 of them shortly after launch, and the list reads like a love letter to Batman history, internet culture, and cinema in equal measure.
Here are 15 of the best.
The movie references that go deeper than you'd expect
The most obvious layer of Easter eggs involves the Batman films themselves, but TT Games goes well beyond the expected winks. Early in the game, a character sprints across a cutscene holding a sparking bomb above his head. That's a direct nod to Adam West's 1966 Batman: The Movie, where the Caped Crusader famously can't find anywhere to safely dispose of an explosive without endangering nuns, a brass band, or a family of ducks.
The 1966 movie gets another callback when Shark Repellent Batspray appears in chapter two. That gag weapon was lifted straight from the same film, and TT Games deploys it with zero irony.
One of the more quietly funny film references is tucked inside Shreck's Department Store, where an elevator plays Danny Elfman's Batman theme as background music. Catwoman's whip attack on store mannequins also mirrors the decapitation scene Michelle Pfeiffer performed in Batman Returns. The attention to detail here is real.
The arcade cabinet high score screen is arguably the best movie reference in the whole game. Five names fill the leaderboard, each pointing to a different Batman actor. Christian Bale (CHR) leads with 9,000 points, Robert Pattinson (PAT) is close behind, and Val Kilmer (VAL) holds third. Ben Affleck (AFL) sits near the bottom with just 500 points, which feels like an editorial comment. George Clooney didn't make the board at all.
Pop culture gags that kids will completely miss
This is where Legacy of the Dark Knight gets genuinely funny for adult players. Alfred answering the phone at Wayne Manor by sliding into frame in just a baggy shirt is a direct recreation of Tom Cruise's most iconic shot from 1983's Risky Business. The American Psycho reference is even more age-inappropriate: Wayne Tower employees obsess over Bruce Wayne's business card, quoting lines verbatim from the film's famous scene.
During the Batman Begins section, Ra's al Ghul quotes the "very particular set of skills" speech from Taken. The joke works on two levels because Liam Neeson played Ra's al Ghul in Batman Begins and also starred in Taken. The game knows exactly what it's doing.
The phone booth at Bat-Mite's store is priced at 2,002 studs, referencing both Bill and Ted's time-traveling phone booth and the 2002 film Phone Booth starring Colin Farrell, who later played the Penguin in The Batman. That's three references layered into a single price tag.
Check Bat-Mite's store dialogue carefully. He occasionally attempts the Resident Evil 4 merchant's "What are ya buyin'?" line, which is easy to miss if you skip past the shop.
The DC Comics deep cuts
The Flugelheim Museum section is essentially a DC Comics history lesson disguised as a level. Among its exhibits are a shard of Kryptonite, a Green Lantern's lantern, and Wonder Woman's Lasso of Truth. A framed copy of Detective Comics Issue #27, the first comic to feature Batman, hangs on the wall, though in-universe it shows The Gray Ghost on the cover instead.
A painting nearby depicts Bill Finger and Bob Kane, Batman's creators. Next to it is Frank Miller's The Dark Knight Returns with its iconic lightning bolt cover.
One of the more obscure business signs in Gotham reads "Miller and Moore: Attorneys at Law." That's Frank Miller and Alan Moore, two of the most influential Batman writers in comics history, reimagined as lawyers. Given that Miller wrote The Dark Knight Returns and Moore wrote The Killing Joke, putting them in a crime-adjacent profession makes a certain kind of sense.
The museum hides DC Comics history
The internet memes hiding in Gotham's streets
TT Games clearly has someone on staff who spends too much time online, and that's a compliment. Halle Purry missing cat posters appear around the city, a joke about Halle Berry's Catwoman being completely absent from the game. The posters are everywhere, making the gag impossible to miss once you know what you're looking at.
Michael Caine's famous Twitter typo gets immortalized in the Batcave. Alfred may quote the tweet in full: "Why do we fall? So we can learn to pick ourselves up. Batman Begin." Caine accidentally dropped the 's' from Batman Begins when posting about the film, and the internet never forgot. Now neither will Legacy of the Dark Knight.
The Donkey Kong obstacle course in Haley's Circus, where Robin dodges rolling barrels on a Nintendo-style ramp, is a great gaming reference. Two-Face then calls out "How'd you like to see a barrel roll?" quoting Star Fox 64's Peppy Hare. The game also opens one level as a close replica of Arkham Asylum's intro, complete with a chained Joker being wheeled through the halls.
The full list runs to 48 confirmed details, and that almost certainly isn't everything. If you're hunting collectibles while exploring, the all collectibles guide will help you cover the ground systematically, and given how dense the world is, you'll want to budget serious time for it. The how long to beat guide puts the main campaign at around 15 hours, with full completion pushing well past 50. There's a lot of Gotham to comb through.
