In the glittering landscape of the 77th Cannes Film Festival, director Christophe Honoré’s “Marcello Mio” made its world premiere on May 21, 2024, offering a uniquely meta exploration of identity, family legacy, and the mystique of cinema. The film, competing for the prestigious Palme d’Or, blurs the line between reality and fiction in ways that feel both playful and profound.


A Daughter Becomes Her Father
At its heart, “Marcello Mio” tells the story of Chiara Mastroianni, daughter of cinema legends Marcello Mastroianni and Catherine Deneuve, who decides to live as her father during a summer of personal upheaval. She adopts his mannerisms, his clothing, his voice – breathing new life into his presence so convincingly that those around her begin to call her “Marcello.”
What makes this premise extraordinary is that Chiara plays herself, alongside her real-life mother Catherine Deneuve, with other notable French actors – Fabrice Luchini, Nicole Garcia, Benjamin Biolay, and Melvil Poupaud – also appearing as versions of themselves.

Genesis of an Unusual Project
During the Cannes press conference, Honoré explained the origins of his project: “With Chiara, film after film, we grew very close. I think it’s the sixth time we worked together, the seventh time in fact – eight if you include a play in the theatre.” This deep collaborative relationship allowed for the unusual pitch that became “Marcello Mio.”
“I wanted to talk about the work of actors,” Honoré continued, “this idea of what’s the identity of an actor… What is it like to spend your life using the identity of others? What does that create in terms of joys, pleasures, and difficulties or troubles?”
Rather than creating a conventional biopic about Mastroianni, Honoré approached the material differently: “I didn’t want to read biographies of Marcello Mastroianni. I didn’t want the film to be a biopic in any way or to talk about his private life. I would have had the impression it was a form of betrayal.” Instead, as he put it, “I sort of dreamed the life of Marcello.”

The Actors’ Experience of Playing Themselves
For Chiara Mastroianni, the project was immediately intriguing despite its unusual nature. “I was deeply intrigued. I found this very daring, very bold, audacious,” she revealed. “It’s a risky wager in fact because when things are so very different, you never know.”
The trust built between actor and director over years of collaboration was essential: “When you’re fortunate enough to have someone with whom you work on the basis of such absolute trust, it’s wonderful. Things seem self-evident.”
Perhaps most revealing was Chiara’s confession about the transformation: “What was troubling however was to note that I didn’t enjoy becoming myself again. I didn’t like becoming Chiara again. I kept saying, ‘Well, can’t I be Marcello?’ I still haven’t sorted that out.”
Catherine Deneuve, when asked about the emotional impact of revisiting relationships with Marcello through the film, maintained professional distance: “I always try to stand back from things. If I let myself be swept away by emotion, I would end up making a film just for myself, which wouldn’t interest anybody else at all. So I thought it would be elegant vis-à-vis the audience to stand back a bit from my part.”
Character vs. Reality
A fascinating thread throughout the press conference was the distinction between the actors’ real selves and their on-screen personas. Melvil Poupaud noted, “We have our names, our image in the film, but sometimes we’re very different. I had the impression I was playing the part of a different Melvil.”
Fabrice Luchini similarly expressed surprise at his character: “When I got this script, I said to Christoff, ‘I was surprised by my part because I’m not known as this version of myself.'”
Nicole Garcia added to this theme: “I don’t think I’m the way I appear in the film. I’m not that brutal, no, not at all… I’m quite shy with actors, I’m very sensitive, and I’ve never found myself in a situation like the one in the film.”
The Magic of Italian Cinema
Honoré’s film also serves as a love letter to the golden age of Italian cinema. “I watch lots of Marcello Mastroianni’s films,” the director shared, “and when you watch the incredible films which we all know so well that date from the 60s and 70s, when you’re a director, you say the film industry was magical at the time.”
This magic inspired Honoré’s approach: “I hoped in a fairly gentle way that I would be able gradually in the film to create something which would be like a sort of spell… I wanted all the actors in the film to become sort of fantastical creatures with very moving frontiers and borders between real life and fiction.”
Behind the Scenes
Production on “Marcello Mio” began on August 21, 2023, in Paris before moving to locations in Italy, including Rome, Latina, and Formia – the latter a city dear to Marcello Mastroianni himself. The eight-week shoot wrapped on October 13, 2023.
The 120-minute film was produced by Philippe Martin through Les Films Pelléas in partnership with Bibi Films, Lucky Red, France 2 Cinéma, Super 8 Production, LDRP II, and TSF.
A Universal Story in Personal Packaging
Despite its highly personal foundation, the film touches on universal themes. As Chiara explained regarding family dynamics portrayed in the film: “This film talks about family ties which we all know and have experienced. It’s something that’s very universal. It’s this question of belonging to your parents via resemblance with one or the other.”
For Honoré, the collaborative spirit of filmmaking shines through in “Marcello Mio.” He revealed his appreciation for spontaneity on set: “The ideal time when making a film is the actual filming… I cherish the moment personally when the actors improvise. I know that something special is going to happen.”
This blend of structured screenplay and organic moments creates what Honoré describes as the magic of cinema: “It’s a huge pleasure as a director. I think it’s a pleasure for the audience to see that suddenly life is there, and life is portrayed by the film, by the cinema. That’s how I view my work as a director.”
