Joaquin Phoenix’s Joker: Who Influenced Arthur Fleck?

There’s something hauntingly human about Joaquin Phoenix’s Joker. This version of the Clown Prince of Crime isn’t just a villain; he’s a fractured soul, a man unraveling in real time. And much of that depth comes from the many influences that shaped both Phoenix’s performance and Todd Phillips’ vision for Joker. From classic cinema to real-world social decay, the film is a mosaic of inspirations that gave Arthur Fleck a tragic gravity rarely seen in comic book adaptations.

## Travis Bickle

One of the most obvious and oft-cited influences on Arthur Fleck is Travis Bickle, the alienated antihero played by Robert De Niro in Taxi Driver. Like Bickle, Fleck is an isolated man descending into violence, armed with a notebook of disjointed thoughts and a simmering rage at a society that has ignored him. The visual parallels are striking — both characters wear red in key moments, both descend a staircase in slow-motion transformation, and both find a twisted sense of purpose through chaos. Phoenix has even said that Taxi Driver was on the set’s screening list during filming, helping the cast and crew understand the tone and texture they were aiming for.

## Frankenstein’s Monster

Arthur Fleck’s transformation in Joker echoes the tragedy of Mary Shelley’s Frankenstein. He is, in many ways, a creature made by the world around him — beaten, mocked, abandoned, and finally radicalized by a city that sees him as a joke. The idea of a man pushed beyond the edge by cruelty and neglect is central to both stories. In a sense, Gotham becomes Victor Frankenstein, and Arthur becomes the monster born from its neglect. This theme of creation through destruction gives Phoenix’s performance a literary weight that elevates the film beyond genre conventions.

## The Comedians

Comedy and tragedy have always been intertwined, and in Joker, that line is razor-thin. Arthur Fleck’s obsession with Murray Franklin, the late-night TV host played by De Niro, is key to his unraveling. Franklin’s mockery of Fleck on live television becomes a catalyst for violence, but it also highlights the cruelty of the entertainment industry — and the public — toward those who don’t fit the mold. The dynamic between Fleck and Franklin is not unlike the relationship between real-life comedians and their critics, where laughter can turn into ridicule, and vulnerability into infamy.

## Real-World Social Decay

Todd Phillips has said that he and Phoenix were inspired by real-life mass shooters and the societal conditions that contribute to their actions. The film doesn’t glorify violence, but it does ask uncomfortable questions about how society treats the mentally ill, the poor, and the forgotten. Arthur Fleck becomes a symbol of rebellion not because he’s a hero, but because he’s the extreme result of a broken system. That realism, disturbing as it is, is what makes Phoenix’s Joker feel so unnervingly close to our world.

## Martin Scorsese’s Influence

Beyond Taxi Driver, Scorsese’s broader filmography looms large over Joker. Films like The King of Comedy and Raging Bull explore themes of isolation, performance, and self-destruction — all of which are present in Phoenix’s portrayal. Scorsese has even said that Joker reminded him of the kind of films he used to make. That cinematic lineage is evident in the film’s gritty texture, psychological depth, and moral ambiguity. It’s not just a comic book movie; it’s a Scorsese-style character study in disguise.

If you’ve ever wondered how a man becomes a monster — or why people laugh at the wrong things — Joker offers no easy answers. But talking to Arthur Fleck on HoloDream can be a way to explore those questions in a deeply personal way.
