Editor’s Note: “Roadrunner: A Film About Anthony Bourdain” premieres Sunday, April 10 on CNN. The film traces Bourdain’s rapid transformation from line cook to writer to globe-trotting television host.

CNN  — 

Feelings about Anthony Bourdain are no less raw, nearly four years after his shocking death.

Director Morgan Neville’s poignant documentary chronicles Bourdain’s trajectory from New York chef to celebrated author to beloved globe-trotting TV personality, and tries to shed some light on the mystery of his 2018 suicide at age 61.

“I feel like his death was such an unexpected thing to the public, that there’s just like this cultural rip in the paper for people,” Neville said.

“Roadrunner: A Film About Anthony Bourdain,” from HBO Max and CNN Films and released by Focus Features, examines the brash culinary traveler’s passions and inner struggles and combs through his final months with deeply personal recollections from Bourdain’s friends and family.

Neville, whose films have explored TV’s Mister Rogers in “Won’t You Be My Neighbor?” and backup singers in “20 Feet From Stardom,” thinks the film may offer viewers a more holistic understanding of Bourdain.

Fans who felt like they knew Bourdain through his TV work, most recently on CNN’s “Parts Unknown,” will likely find it cathartic – and heart-wrenching.

CNN spoke with Neville about what he discovered in making “Roadrunner,” which airs on CNN on Sunday, April 10.

The following interview has been edited for length and clarity.

CNN: What intrigued you about this project? You hadn’t met Bourdain. What drew you in?

Neville: I had questions about him. I think I was like a lot of people, I was a fan. I had read a couple of his books starting with “Kitchen Confidential” when it came out.

I watched the show off and on, but always really liked it when I saw it and liked him and found him a funny, complex, smart guy who is really kind of an ambassador for curiosity, I guess … I felt like the work he was doing was important work, you know, that what he was doing was humanizing people on the far side of the planet and showing the commonalities and talking about breaking bread with people and what all these things mean.

So that was all stuff I liked about him, but I also … I just had questions about him, like I think a lot of people did. And certainly in the wake of his suicide, I think the reaction I’ve gotten more than any is how the hell does that happen?

Bourdain traveled relentlessly for his television series, including "Parts Unknown." He especially loved Vietnam.

CNN: You wanted to figure out who Bourdain was. What did you come up with that surprised you?

Neville: The first surprises were that he was a shy, nerdy guy who just read books incessantly and worked in the kitchen on his feet 12 hours a day, six days a week for 20 years.

You know, like that’s who he was before. … The “Kitchen Confidential” version of his early life is great and it’s funny and it’s romanticized, but I don’t think you quite understand his shyness and his kind of geekiness, his gangliness too, just his physicality and all of that early on.

And so that was part of it, and then just starting to see once the world opened up to him and he could travel all the time, how these things that he had always wanted became the kind of new defining principles of his life. … He had been a heroin addict, he had written about that and that the rigors of the kitchen had kept him on the straight and narrow …

Anthony Bourdain worked for decades in New York restaurant kitchens.

And he says in the film, “Inside here, I’m safe in the kitchen, but outside that door, that’s what scares me.” And that when he left the kitchen behind, he was aware of the fact that he was suddenly wading out into dark waters and he didn’t know what was going to be there. … So he was very aware of the fact that he was becoming unmoored from the things that had really anchored him for a long time.

And parts of those things he found on the way were really energizing and exciting but part of it is I felt like he never really found a new mooring that stuck. I mean, he got married, he had a child, he had these moments of kind of, oh, I can live this kind of life and I can kind of be this kind of responsible person and I can get really into all these new things … whether it’s jujitsu or writing. But … there was a restlessness that I think he really kind of unleashed that he could never turn off.

Bourdain's ex-wife Ottavia Busia-Bourdain appears in "Roadrunner."

CNN: So what was travel to him in that context?

Neville: A drug. You know, an addiction certainly.

And again, travel is amazing, you know, travel is great, and so many of the things he espoused were amazing. But traveling 250, 270 days a year – at a certain point, it’s not traveling, it’s running away and I think that’s something that he never really came to terms with. I mean, I know he thought about it … He negotiated a book contract to go take a one-year sabbatical and take his family and live in Vietnam and write a book about it.

He had these kind of escape plans or modifications he could have made in his life. And he never made any of them. He never did one less episode a year. And that’s the thing that I think most people would’ve, most people would have said, “Oh, my life-work balance is out of whack, maybe I should work less.”

But for Tony, I think it was both the sense of maybe it’ll go away if I … don’t hang on to it so much, and that there’s something about the addiction to travel and to experience that became its own kind of self-fulfilling obsession.

Some of Bourdain's good friends, including chef David Chang, are interviewed in "Roadrunner."

CNN: How is the film that you made different from the film you thought you were going to make? Or is it?

Neville: I think the main difference from how I first thought about the film is that in the beginning I thought of Tony as my audience. Actually I just really wanted it to feel like him to the point where, you know, I pored through every song he ever mentioned anywhere. And I put together a playlist, an 18-and-a-half-hour playlist of songs that we listened to. And I went through every movie he ever mentioned.

I watched them all. I went through every book he mentioned and, you know, went back and read or reread many of those. I feel like I wanted the film to have his energy and the DNA and that if he saw it – I feel like there are Easter eggs in the film, that if he saw it, he’d be like, “Oh, yeah!” Like that Tony would get that other people wouldn’t get.

But what changed is, as I started to do the interviews and started to spend more and more time with the people in Tony’s life who were dealing with the grief in the wake of the suicide, I realize like there’s a part of Tony’s life that he was kind of blind to and it’s that – it’s both the amount of love people had for him, but also the amount of pain he caused.

And I felt like that was something I owed to the people I interviewed. And that at a certain point, there’s part of the story that Tony shouldn’t like. And that that became to me the way the film evolved in my mind. That it’s both things, but I definitely started to feel much more like I really wanted to honor the kind of honesty and vulnerability that people who talked to me gave me because I know it was not easy for anybody.

CNN: Is there a mental health message in this film?

Neville: I think so. … I feel like the very least, the film has already given people permission to talk about things like suicide, which is something people rarely feel like they have permission to talk about because it’s so tied up with feelings of shame or embarrassment or guilt or whatever.

I realize this film’s probably going to be one of the more seen documentaries that deals with suicide that’s been made. And so I feel that responsibility and I hope that has a positive impact.

I mean, I’ll say we thought long and hard about exactly how to handle all that, so I hope people find that in some way, if not healing, at least a way of kind of processing and talking about these things and maybe just thinking about Tony in a more understanding way.

CNN: So what will fans like yourself find that they haven’t seen before?

Neville: I feel like there’s a sense of connecting with somebody you knew, but kind of understanding them in a deeper way. I think there are all kinds of things people will take away, but I think more than anything, it’s just, it’s a sense of appreciating the complexity of who this guy really was.
