The film introduced pop superstar Lady Gaga as Dr. Harleen Quinzel, who transforms into Harley Quinn, the Joker's psychiatrist and eventual partner in crime. The title, Folie à Deux, is a French term meaning "madness for two," perfectly encapsulating the shared psychosis and intense, destructive relationship between the two main characters. Phoenix’s dedication to the role, including the physical and emotional toll of the musical numbers, was once again lauded by critics and co-stars alike.

Ari Aster’s Eddington and Other Current Projects

In 2025, Joaquin Phoenix continued his tradition of working with visionary directors by starring in Ari Aster’s highly anticipated film, Eddington. Aster, known for his unsettling and complex horror films like Hereditary and Midsommar, took a sharp turn with this project, which is described as a dark comedy set in a fictional New Mexico town.

The film’s ensemble cast is a powerhouse, featuring Phoenix alongside other major names like Emma Stone and Pedro Pascal. The movie premiered in mid-2025 and was met with strong reviews, further solidifying Phoenix’s reputation for choosing challenging, director-driven projects. His performance in Eddington was noted for its departure from the high-intensity roles of *Joker* and *Napoleon*, showcasing his versatility.

The Dropped Project and 2026 Rumors

While Phoenix is known for his commitment, he also maintains a selective approach. In a recent piece of industry news, it was reported that Phoenix had dropped out of a film by director Todd Haynes, a project that was subsequently halted. However, the film, now reportedly titled De Noche, has been revived for a potential early 2026 filming in Mexico, with The Last of Us star Pedro Pascal in talks to replace Phoenix. This shows the constant, fluid nature of high-level Hollywood production and the difficulty of securing an actor with Phoenix's demanding schedule and artistic standards.

Another confirmed project on his slate is The Island, though details and a release date remain largely undisclosed (TBA). This continuous flow of unique and often dark projects ensures that the actor remains one of the most compelling figures in Hollywood's current landscape.

Private Life, Public Stance: Rooney Mara and Activism

Despite his volatile and public on-screen persona, Joaquin Phoenix is famously private in his personal life, preferring to use his platform for social and environmental advocacy rather than celebrity fanfare. This contrast between his work and his life is one of the most intriguing aspects of his public image.

Phoenix has been in a long-term relationship with fellow actor and frequent co-star Rooney Mara since 2016, having met on the set of the 2013 film Her. They are one of Hollywood’s most low-key couples, valuing their privacy immensely.

In a rare public appearance, the couple was photographed together at a charity gala, a moment that quickly drew attention due to their usual avoidance of the spotlight. They share a son, River, named in tribute to Phoenix's late brother, River Phoenix.

Beyond his family life, Phoenix is a passionate activist. His veganism, which he has practiced since he was a young child, drives his environmental and animal rights work. He often uses his acceptance speeches at major awards ceremonies, including his Academy Award win, to speak out on issues like climate change and the ethical treatment of animals, further cementing his status as an artist whose influence extends far beyond the silver screen.
