The Canadian actress Petrina Bromley has been in the cast during the show’s surprise hit run on Broadway. It resonated because “it’s about kindness,” she says.On Sunday afternoon, “Come From Away” played its final performance on Broadway, before a raucous sold-out crowd that wept and waved. By Monday morning, stagehands were already taking down and hauling away the real trees that gave the Schoenfeld Theater its forested look.Petrina Bromley, the lone Newfoundlander in the cast, returned to the theater to collect her belongings and to talk about the show, which told the true story of how Gander, Newfoundland — a small Canadian city with a big airport — sheltered thousands of airline passengers forced to land when trans-Atlantic flights were grounded by the terrorist attacks of Sept. 11, 2001.The musical, written by Irene Sankoff and David Hein and directed by Christopher Ashley, opened in 2017 and became a surprise hit, with its message of generosity and community resonating at a time when those values seemed in short supply.Bromley, like all members of the cast, played multiple characters, but she is best known as Bonnie, the woman who ran the local animal shelter, and wound up caring for the dogs, cats and two bonobos that had been onboard the planes. (Among the items in her dressing room: a variety of bonobo-related gifts sent by fans.)A scene from “Come From Away,” near the start of its Broadway run. Bromley said that when she first heard the creators’ idea for the show, she thought, “Good luck to you.”Sara Krulwich/The New York TimesBromley, 51, has been with the show off and on for seven years, throughout its development and the Broadway run. All told, she has been in 1,514 performances of “Come From Away,” including pre-Broadway runs in San Diego, Seattle and Toronto as well as 1,362 Broadway performances. She has also been part of two concert presentations in Newfoundland — one before the Broadway run and one last month — and she was part of the cast of the filmed version, shot during the pandemic shutdown.Her status as a Newfoundlander — she is a career Newfoundland actress who was raised on the island and is returning there now that the show has closed — gave her a unique perspective on the show. These are edited excerpts from our conversation.How are you doing?It’s a lot, right? I thought yesterday would be hard, but this is actually harder. The trees are being felled. I’ve come and gone from the show a bunch of times but the space itself has always been here. And now it’s not going to be here anymore.You wound up in the show because you met the show’s writers in Gander on the 10th anniversary of Sept. 11?I was in Gander with a local theater company, Rising Tide Theater — we were doing something as part of those events. We walked into the one coffee shop that wasn’t a Tim Hortons, and the only other people in there were this young couple sitting at a table with cue cards, organizing themselves to do an interview. I had the same reaction everybody in Gander had: “Good luck to you. I’m not sure how you’re going to turn that into a show, but have at it.” We stayed in touch through Facebook and stuff like that, and they saw me in a couple of shows in Toronto, and I was invited to audition.Apparently the audition went well.I was on the other side of the doors, waiting to go in, and some incredible person with an incredible voice sang “Let It Go” so incredibly well and loud and high and my inner monologue was, “What are you doing here?” So I abandoned my book and said to them, “You know, I think considering what the show is, and who I am, and where I’m from, I should sing you a song from Newfoundland.” So I sang a very silly song about a talking goat [“The Mobile Goat,” recorded by Joan Morrissey]. I think they were a little confused by it, but it was certainly something they hadn’t heard. And I do credit that tune with getting me the job in the end.Bromley talking with fans outside the theater on Sunday. “People do tell me their pet stories all the time, and it’s beautiful,” she said.Jeenah Moon for The New York TimesYou had some apprehension about how Newfoundland was going to be depicted.When you have a culture that is distinct, it’s easy for it to be stereotyped. So the accent, and being poor, and being undereducated became the marks of what it is to be a Newfoundlander. In Canada, the “Newfie” joke was a big thing for many, many years, and we were often portrayed in the media and pop culture as stupid Newfies. That was my concern: Here are some mainlanders — “Come From Aways” — coming down to tell a story about us, and how are they going to paint us? But at the very first rehearsals in La Jolla, Chris Ashley made it very clear he wanted every character in the show to be treated with respect and not to be just cartoons. And as soon as he said that, I was like, “It’s all going to be fine.”When this show was in development, there was a lot of skepticism about whether it could work commercially.Absolutely. I’ve been skeptical the whole time. I was always wondering about the sheer earnestness of it, in a world that is as cynical as our world is. And telling a story about 9/11 in New York to New Yorkers — there was a lot of concern.Why do you think the show worked for as long as it did?Because it is about community, and it’s about kindness. There are no dragons and no helicopters and no wizards. This show raised up ordinary people doing very simple ordinary things — just helping each other out — and particularly in the past five or six years, with what’s been going on here in the States and around the world, kindness and generosity are things that we’re losing sight of.You played a woman who runs the local Society for the Prevention of Cruelty to Animals. Are you an animal person?I have three dogs. I have allergies or I would have a million pets. People do tell me their pet stories all the time, and it’s beautiful. It’s a lovely way to connect.Did you ever meet Unga, the bonobo most discussed in the musical?She passed away before I was able to go to the zoo. If the pandemic hadn’t put a roadblock up, I would have been there to meet her. But I did meet Unga’s son Gander, and her other son Jerry, at the Columbus Zoo [in Ohio]. Bonnie and I went together and watched them in the enclosure. It was incredible.What is the level of awareness of the show in Newfoundland?You can’t not be aware of it — it’s everywhere. We just did those concerts back home — three shows in Gander and three shows in St. John’s, at large arenas, which sold out in minutes. Hundreds, possibly thousands of people have made the pilgrimage to come see it here or in Toronto or in places across the country where the tour was happening. It’s made its way into being part of the culture now. And everybody wants it to have a further life in Newfoundland.Bromley, center, at the final curtain call with Bonnie Harris, the woman she portrayed in the show.Jeenah Moon for The New York TimesWhat was your career like before this show?I thought it was fine! I was a very employed, everyday working actor in Newfoundland, which is not easy to do. I had enough of a reputation and experience to be consistently working, mostly in theater, sometimes in TV and film. And I thought that that was as good as it gets. I still feel that way. I’m going home, back to Newfoundland, hopefully to fall back into working with the people that I love who create new, incredible work all the time.What is your career like now?I’m much more recognizable at home, which is lovely. I picked up a TV series back home, called “Son of a Critch,” and we just finished filming the second season of that. I’m a tertiary character, but it’s a lovely little gig to have and hopefully that can blossom into other things. I don’t have an agent, and I never have, and I have worked in Stratford [in Ontario] and on Broadway. But I’m probably going to get an agent so that I can work across Canada.What surprised you about Broadway?While I do have a lot of reverence for it, if you hold things on a pedestal, when you get there in a lot of ways it’s the same thing: It’s a job that you go to every day. I appreciate, being the age that I am, to have had the experience to know that it was going to have highs and lows, and that there would be ordinariness inside of the extraordinariness. And I’m always aware of the privilege of it, and the reality that none of us would have been on that stage but for the fact that a very tragic event happened and thousands of people died. And grateful that I got to tell a story, connected to them, that kept their memories alive in any way, shape or form for people who needed to hear it.What did you learn about New York City?It’s crazy. It’s great. To live in New York was incredible. But again, the layers get peeled back when you live somewhere, and you see that it isn’t just a helluva town. I found it difficult on many levels. To be in a very privileged position of working at this incredible place, but literally walking past the most desperate individuals I’ve ever seen in my life, people who are in jeopardy, on the street, asking for help, and we all walk past them and no one helps them. To come and tell this story, where giving a helping hand makes sense, and watch it not happen in reality on the street, I’ve found that hard to reconcile.Have you changed?Absolutely. In many, many ways. I like to think that I’m a bit more generous, a bit kinder than I was before this. It’s also made me a better singer. It’s made me a better actor. And certainly the cosmopolitan experience of living in a big city has changed me.Why are you going back?Because it’s home. There’s a joke about Newfoundlanders: “How do you know the Newfoundlanders in heaven? They’re the ones who want to go home.” More
