It's only been a matter of days since the Joker movie hit screens, and already it's stirring up controversy.

The psychological thriller details the origin story of Batman's archnemesis, The Joker, and how he became the notorious villain he is. But, while the eagerly-anticipated movie has been a huge hit so far, it hasn't been without its criticism, with many people calling out the film for its representation of mental illness - with some saying that it's so dark that people are walking out of theatres.

But the movie's success has created a huge and unlikely tourist attraction, with hundreds flocking to the location to get the perfect Instagram snaps. Keep scrolling to find out more...

The Joker is one of the most infamous villains in the comic book world.

The supervillain made his debut in the Batman comic books in 1940 and has since become one of the most notorious faces of the franchise.

He was originally meant to be killed off during his initial appearance.

But plans changed and he stuck around to become Batman's archenemy.

He was most famously brought to life by Heath Ledger in 2008.

The Dark Night was a box office smash hit, receiving rave reviews and grossing over a staggering $1 billion in revenue.

The movies the Joker appears in seem to garner worldwide success.

Seems fans of the franchise can't get enough of the psychopathic anti-hero.

So, when it was annouced he was getting a movie of his own...

This time, the infamous criminal mastermind is portrayed by Joaquin Phoenix.

Speaking to Ladbible, the Oscar-nominated actor explained: "I thought it was important for it to be its own thing, to be its own interpretation. What's interesting about this character is that everybody can interpret it however they want.
"Even with this film, I think the audience gets to interpret the character and what drives him, in a way that I think is unique for a lot of films. I mean it really asks the audience to participate, and I think that's interesting."

The movie hit screens last week.

Directed by Todd Phillips, Joker tells the origin story of, you guessed it...the Joker (or Arthur Fleck as he's known as in the movie), and how he evolves into the criminal mastermind we all know him as.

Arthur Fleck is a lonely, failed comedian.

Set in 1981, Fleck, who is working as a party clown, lives with his mother in Gotham City - a town full of crime and unemployment.

Fleck also has a neurological disorder that causes him to laugh at inappropriate times.

Due to this, he often lands himself in bad situations. And of course, he finds himself on a huge downward spiral.

He becomes an outcast of society.

Fleck is isolated, bullied, and lonely.

The movie chronicles his descent into madness.

Soon enough, Fleck's life becomes rife with out-of-control into delusions, violence, and anarchy and thus, the clown-faced criminal is born.

The movie has solicited some extreme reactions.

From rave reviews to full-blown outrage, the dark movie has debuted to extremely mixed emotions.

The movie has already broken a major record...

via: imdb

Over the weekend alone it raked in an eye-watering $93.5 million at the US box office - although we aren't entirely surprised, given the huge anticipation in the lead up to its release.

But given its blatantly dark and, at times, sensitive themes, it was bound to whip up some kind of controversy.

And it sure didn't disappoint, with many people slamming the movie for its representation of mental health and "glamorization" of violence.

Theatre-goers have also been left outraged by a particular song used in the movie...

Convicted pedophile, Gary Glitter's 1972 "Rock and Roll Part 2" is used in one scene. Glitter was jailed in 2015 for a number of sexual assault offenses, including one count of raping a 13-year-old girl, so it's no wonder so many viewers were disgusted.

The movie is apparently so disturbing, it has been leaving viewers unable to continue watching.

Several people took to Twitter to call out the "horrible" movie, saying how they've been left terrified while watching.

It seems to have rattled many people...

While some have praised the movie for shedding light on the struggles of living with a mental illness, others didn't agree and think the film's portrayal did more harm than good.

Several have been saying the movie should have come with a trigger warning.

Like this user, who cited the graphic shooting as one of the main reasons why they feel a trigger warning should have been placed at the start of the movie.

Other's cut the movie more slack.

While many admitted that the movie was without a doubt dark and disturbing, some say Joaquin Phoenix's performance deserved an Oscar. And it seems as if the news might be on the brink of coming true... Three cheers for Joaquin Phoenix!

In my humble opinion, I say you give that man an Oscar right now.

It's not even been a week since the movie hit the big-screens but it has already managed to crawl its way into the top 10 films of all time. According to IMDb rankings, Joker is now considered one of the best movies to ever exist coming in at 9.

Joker is slowly pushing its way into the top-tier.

The film currently stands at an 8.8 rating standard, with many Pheonix fans hoping that it will continue sneaking up until it falls into the top 5 films of all time.

But it's not just the movie ratings and the controversy that is causing Joker go viral...

It's actually the stairs that Phoenix dances down in the movie - which are also the same stairs on the movie's front cover - that have become a huge tourist attraction.

It's time to forget the Statue of Liberty...

The Joker stairs are located in The Bronx in New York City and connect Shakespeare and Anderson avenues at West 167th Street.

Fans have wasted no time in visiting the Joker stairs...

And they have been proudly sharing their Joker-themed photoshoots on social media.

Many are clearly just excited to be there...

And the die-hard fans have traveled many miles to stand on the infamous Joker steps.

But a lot of people have been giving their best Joker impressions...

And some of the results look pretty amazing.

But many seem to not realize that the stairs are in a residential area...

So an area filled with family homes and schools has now been mobbed with enthusiastic Joker fans... not ideal, really...

And despite the fans' enthusiasm...

Not everyone is impressed.

It has probably gotten a little annoying for local residents...

Some locals in the area have voiced their frustrations, such as Twitter-user Desus Nice, who recently wrote: "Legally as a Bronx resident you're allowed and encouraged to tax anyone visiting the joker stairs." 

It has to be said, it's a pretty nice effort on the fans' part.

Who knows if the hype will eventually die off, or if the Joker stairs will become a timeless tourist attraction? Only time will tell...
