Fans are freaking out after spotting secret detail in new Joker 2 trailer revealing massive hidden character

Joker may be an Oscar-winning film, a Golden Lion winner at the Venice Film Festival, and a billion dollar movie.

But at its core, it’s still a comic book movie, so when you make a sequel – fans are going to be tearing apart everything you release to try and find hints of new characters.

With the new trailer releasing for Joker: Folie à Deux today, DC fans have already began pouring over the footage to see what they can find.

Check out the trailer below and see what you come across:

One specific detail in the trailer though reveals a massive hidden character, and you wouldn’t come across it by watching the trailer above.

The only way to find it is to go on YouTube, add closed captions, and keep a close eye on who says what.

As first reported by DiscussingFilm on X, the closed captions on the trailer reveal the mysterious voice talking about the Joker, aka Arthur Fleck.

The reveal showed that the mysterious voice belonged to none other than Harvey Dent.

I’m sure half of you will have lost your mind at that reveal, and the other half will be going ‘who’?

Fitting as that is, Harvey Dent is perhaps better known as Two-Face, the former Gotham DA who becomes an often split supervillain.

This does make sense with what we’ve seen of the film, with the new trailer revealing part of the movie will follow Arthur Fleck’s ‘trial of the century’ for his crimes in the first Joker, presumedly being prosecuted by Dent.

Fans on X have, to put it lightly, lost it.

One fan posted: "Harvey Back?! I’m definitely watching this."

The last time Dent appeared in a live-action Batman film was when he was brilliantly played by Aaron Eckhart in The Dark Knight.

Another fan said: “The introduction of Harvey Dent adds a fascinating layer to the narrative.”

With the film set to be a jukebox musical according to reports from Variety, some think this will suit the character to a tee.

One reply said: “Cool, hope he sings with two different voices while shimmying to the side showing both different sides of his face”.

Whilst the actor playing the role has not been confirmed, there are rumours already flying about who could take on the multi-dimensional character.

The leading theory is that Harry Lawtey, who came to prominence for his role in Industry, will play the role.

Whilst Lawtey has been announced as part of the supporting cast for the film, he has not yet appeared in any of the trailers. This has not yet been confirmed at the time of writing.
