The Batman is one of the most anticipated comic book movies on the horizon but what’s the answer to the teaser’s riddle? What does a liar do when he’s dead?

Like with Spider-Man, we’ve had so many interpretations of Batman and Bruce Wayne that it’s getting increasingly difficult to keep track of them all.

While some will always have their favourites, there’s always plenty of excitement when a new Batman film is on the horizon and Matt Reeves’ The Batman is no different.

We were promised a much darker and grittier affair in The Batman and the first teaser, revealed at the DC FanDome event, certainly lived up to the billing as we caught our first glimpses of the film’s supporting characters including Paul Dano’s Riddler, Colin Farrell as Penguin and Zoe Kravitz as Catwoman among others.

However, one moment of the teaser trailer has caught fans’ attention more than any other, a riddle we see scribbled in a greetings card: “What does a liar do when he’s dead?”

Naturally, fans have been quick to get to work on solving the riddle.

The Batman

Set for release in 2021, The Batman looks to take the caped crusader back to his routes as ‘the world’s greatest detective.’

The noir-style story is set to reunite Batman with the Riddler, a villain we’ve not seen on the big screen since Jim Carrey’s cartoonish take on the character in 1995’s Batman Forever.

This time, however, while the garishly green outfit may be gone in favour of a thick coat and a nightmarish mask, Paul Dano’s Riddler still has a few questions to ask of Batman.

What does a liar do when he’s dead?

During the teaser trailer, we catch a very brief glimpse of a greetings card that the Riddler has left for Batman.

Inside is the question:

  • “What does a liar do when he’s dead?”

However, the solution to the riddle is written in a series of symbols which, at first glance, appear to be nothing more than gibberish.

However, keen-eyed Batman fans have taken it upon themselves to crack the code.

Solved: What does a liar do when he’s dead?

  • He lies still

That’s right, the answer to the Riddler’s puzzle is “he lies still.”

The pun is a clever double entendre and can be taken to mean that the liar is not only still because he’s dead but also that he still lies even in death.

Several fans across social media have already solved the puzzle with one fan on Twitter detailing how they worked out the riddle in a four-tweet thread.

The key to solving the riddle here is substituting the symbols out for letters but the question is which ones?

Andrew Lane on Twitter explained that the letters E and L are crucial to unlocking this riddle. E is the most commonly used single letter in the English language while L is the most commonly used double letter.

The Batman is due to release in cinemas in 2021.
