The untold story of the Joker from DC Comics will finally be revealed. In 2019, Todd Phillips, best known as the director of The Hangover trilogy, will unleash Joker, a gritty crime thriller that will explore a failed comedian’s descent into a life of villainy as the famed archenemy of Batman, starring Joaquin Phoenix.

In a time when superheroes bend moviegoing audiences to their will, Joker is poised to dramatically reinvent the popular genre. This isn’t a typical comic book movie. It’s not even trying to ape Logan’s schtick as a neo-western reskinned as a superhero movie. Joker is straight up a crime drama, and is actually a passion project of its lead star.

Here’s everything you need to know about Joker, including its release date and just how in the hell this movie came to existence.

When will Joker be released?

Joker will be released on October 4, 2019.

Is there a trailer?

A trailer for Joker has not yet been released.

Who is playing the Joker?

Three-time Oscar nominee Joaquin Phoenix will star as “Arthur Fleck,” a failed comedian who becomes Gotham City’s most notorious crime boss and serial killer, the Joker. Phoenix is the fifth actor to play the Joker in live-action, after Cesar Romero, Jack Nicholson, Heath Ledger (for 2008’s The Dark Knight, which earned him a posthumous Oscar), and Jared Leto.

Phoenix has been interested in doing a superhero movie for some time, but wanted something really different and smaller than the typical blockbuster.

“Three or four years ago, I called my agent and said ‘Why don’t they want to take one of these characters and just make a lower budget film about it, a movie but a character study, and why not take one of the villains?’” Phoenix told Collider in a July 2018 interview.

Assuming Joker was off the table, Phoenix looked for other characters, and even rejected a general meeting with Warner Bros. “So I completely forgot about it, and so then I heard about this idea, I was like, ‘Oh that’s so exciting, that’s the kind of experience I wanted to have, with a movie based on a comic character.’ I felt like you could get something on screen.”

What does Joaquin Phoenix look like as the Joker?

There’s a whole bunch of photos from the film’s New York and New Jersey sets online, but Warner Bros. and Phillips released an official “teaser” reveal, which you can watch at the top of this article.

What’s the story about? Has Joker’s origin really never been told?

Yes. No. Kind of?

The movie Joker explores how Arthur Fleck — a name never before seen in any Batman media — becomes the Joker. But the Joker’s name has never been revealed, and his true identity remains a mystery. That’s his appeal.

“Jack Napier,” which was the identity of Jack Nicholson’s Joker in 1989’s Batman, was officially given to the Joker in the 2017 miniseries Batman: White Knight, which took place outside DC’s mainstream canon.

Meanwhile, the FOX television series Gotham, which had Cameron Monaghan as “Jerome Valeska,” spent several seasons toying with whether or not Jerome is in fact the Joker that Batman grows up to fight.

Only one Joker origin has defined the popular imagination. In 1988, Watchmen writer Alan Moore penned Batman: The Killing Joke, a one-shot comic that showed how a struggling comedian was tricked into being a fall guy, which led to a horrible accident that turned “Jack” into a psychotic villain.

Despite Moore disowning the work, fans revere The Killing Joke, and its influence is undeniable in Todd Phillips and co-screenwriter Scott Silver’s story.

Does it take place in the DC Extended Universe?

Nope. In fact, it takes place in a different time.

As confirmed by supporting actor Shea Whigham, who plays a Gotham City detective in the movie, Joker is set in 1981. The movie will portray a Gotham City that closely mimics the dirtier, seedier New York City of the same era, when Time Square was called by Rolling Stone “the sleaziest block in America.”

Gotham City will be literally dirty, too. Apparently a subplot of the film involves a mass trash worker strike throughout Gotham, leaving the city’s streets overrun by mountains of trash. Photos of the film’s Newark, New Jersey set reveal production hands piling fake garbage bags for the movie.

So if Jard Leto’s Joker wasn’t your thing, fret not. You won’t have to worry about watching Suicide Squad ever again.

What’s this about Alec Baldwin and Donald Trump?

Yeah, about that. Here’s the gist: For a time, it was rumored Alec Baldwin, who has a pretty mediocre impersonation of Trump on SNL, would play Thomas Wayne — the doomed father of Bruce Wayne — in Joker. Remember, Joker is a distant prequel, its story taking place long before that fated night Bruce Wayne becomes the vengeful superhero we all know and love.

Anyway, it turned out to be false, but emerging set photos and footage of Joker revealed that Thomas Wayne is indeed a Trump-like figure. A big scene shot inside New York subways revealed extras carrying anti-Wayne signs, some of which read “FASCIST WAYNE” and “CLOWN MAYOR.”

It was in the 1980s when Donald Trump emerged as a celebrity millionaire, slapping his name onto lame consumer products and gaudy casinos. It appears in the Joker universe, the Waynes are Gotham’s Trumps. (Does that make Bruce the Eric, Don Jr., or Barron?)

I heard the actors peed on set?

Yeah, there was a really bad situation that happened on set. Extras were allegedly trapped for hours inside a subway car, which was a clear violation of SAG-AFTRA rules. The matter appears to have been resolved.

Is Batman in this thing?

Probably not. But the 1966 version of the Batmobile has been spotted on set for some reason.

Joker will be released in theaters on October 4, 2019.
