Getting Life Advice From Your Future Self, Who Happens to Be Aubrey Plaza: Megan Park and Maisy Stella Chat 'My Old Ass'

"We were just saying, we love an Aussie." When you're My Old Ass writer/director Megan Park and Australia's own Margot Robbie has produced your latest film, it's easy to understand why. Gleaning why she greets Concrete Playground that way isn't hard, either. "We do," adds Maisy Stella, the movie's star. "Yeah, we really, really do," Park chimes back in. Robbie's production company LuckyChap Entertainment, which has I, Tonya, Birds of Prey (and the Fantabulous Emancipation of One Harley Quinn) and Barbie to its name as well — and, among flicks that don't boast its co-founder on-screen, Promising Young Woman and Saltburn, too — is also onboard for Park's next release after this marvel of a coming-of-age tale.

Viewers of My Old Ass have more from Park to look forward to, then. Right now, though, they already have a must-see to enjoy courtesy of her second feature as a filmmaker. Actually, that also applies to her debut. An actor herself, Park initially jumped behind the lens on 2021's excellent Jenna Ortega (Beetlejuice Beetlejuice)-led The Fallout, which plunged into the aftermath of a school tragedy. Now, the former The Secret Life of the American Teenager star has penned and helmed a picture set as its protagonist gets ready to leave her small-town home behind for college.

For her second movie about teens making sense of their world, too, Park embraces a high-concept setup — and one that heads down a universal path that resonates with viewers of all ages. Have you ever wanted to get life advice from your future self? Or, conversely, to give your younger self some words of wisdom, whether about what not to worry about or who to avoid? Focusing on Nashville's Stella as the just-turned-18 Elliott — and featuring Parks and Recreation, The White Lotus and Agatha All Along favourite Aubrey Plaza as the older version — that's My Old Ass' storyline.

If you're wondering how the two Elliotts come to meet, the film uses a mushroom trip to head into magical-realism territory. When they come face to face, Plaza's 39-year-old Elliott has a specific piece of advice for the girl that she once was: stay away from Chad (Wednesday's Percy Hynes White). We all know what happens when you tell someone not to do something, especially a carefree teenager, so of course Stella's Elliott doesn't heed that warning. This is a film, however, that understands the urge to want to send your former self in a certain direction, because it understands what it's like to live with the ups and downs that life takes us on just as firmly. It equally appreciates that it's those ebbs and flows — and joys and hurts as well, so our course for better and for worse — that make us who we are.

What would Stella do if the Sundance Film Festival-premiering movie's premise became an IRL possibility for her? It depends on which way the advice was flowing. Park is of the same opinion. They'd each be keen to talk to their younger selves, but not their older guises.

"I've decided that I reject it. I really reject it. I've been asked this and every time I try to think of something, and I think the reason that I don't have anything is because I would not take the opportunity. I would take the opportunity to meet younger self. But the older, it just feels a little scary to me," Stella tells us. "It gets dicey. See, it goes dark quick. I mean, it really takes a turn," she continues. "Yeah, it's a it's a scary one," agrees Park. "I think I'm going to hard pass on it too, probably. I'd want to go back and meet my younger self."

Thinking about these questions is unavoidable after watching My Old Ass, no matter whether you decide that you'd seize or shirk the chance that Elliott is given. Also part of the viewing experience: wishing that Plaza could pop up in your life either way. We also chatted with Park and Stella about where the idea for the film sprang from, what Park was interested in exploring with it, Stella's excitement about playing Elliott, how she approached the character, and working with both Plaza and Robbie.

On What Inspired My Old Ass, and What Park Was Interested in Exploring

Megan: "I think the themes that I really wanted to explore were grief and time passing, and nostalgia — and motherhood, truthfully, was a big one that I wanted. I was a new mum when I wrote this script, so it was those feelings that were really the entry point into this idea that's so universal, I think, of wanting to talk to your older or younger self.

Or regrets. Regret is another big one. I think I'm such an emotionally driven writer that I'm not thinking about necessarily the structure of the story, and what's going to happen and what are people going to take from the movie — I'm just driven from that emotional place, at least I have been so far in the two movies I've written. It's all I really know how to do it.

So those were the themes I wanted to explore. And then as I didn't know where it was going, as soon as Elliott came to me, and older Elliott, I just followed that lead and figured out the story as I went."

On Stella's Initial Reaction to the Script, and What She Thought That She Could Bring to the Younger Elliott

Maisy: "My first reaction to it was just beaming with excitement. It was funny, because I had been auditioning for so long and I really enjoy auditioning, and I really enjoy reading scripts and I read a lot of scripts at that time, and it was just my favourite thing I'd read in forever.

And I was immediately met with anxiety. The second I started reading it, the thought of it being taken from me, I was like 'no!'. And it wasn't even mine at all. But the thought of not getting to be a part of this amazing project was so scary to me.

So yeah, my initial reaction to it was deeply, deeply moved; really excited and inspired by it; and would have just been so grateful and lucky to have been a part of it. And it worked out for me. I'm very grateful and lucky."

On the Journey to Realising That Aubrey Plaza Was the Ideal Older Elliott

Megan: "Truthfully, I'd written the role for somebody to be much older, like in their late 40s, early 50s. And we cast the film around Maisy, and so we were really stuck on who looks the most like her, who's in that age range and who's available to come to Canada to film the movie. And there just was never anybody that came up that was the right match for the tone of the movie, for energetically with Maisy, for the comedy.

It wasn't until there was a list of names that somebody had suggested, and Aubrey was on there. It was like 'wait a second, I'm such a fan of hers' — and I knew Maisy was a fan of hers. She was not even 40 and doesn't look anything like Maisy really, but we were like 'wait a second', and for some reason the energy and the chemistry was just such a connection. And it just made the whole movie make sense in a whole new way for me.

I'm close to age to Aubrey and I thought 'wow, I've actually never felt older than hanging out with all the 18 year olds'. And there was something so funny to me about this idea that she thinks she's so old and she's not even 40. And even the title became funnier when it was Aubrey."

Maisy: "Yes!"

Megan: "So then, luckily we sent it to her, and only her, and she read it and loved it and wanted to be a part of it. So once we got it to her, the stars really aligned quickly, but it was kind of me getting out of my own way and being like 'wait, instead of worrying about who looks the most like Maisy, who fits into the movie?'."

Maisy: "Instead of worrying about who's blonde?"

Megan: "Yeah, exactly."

On Collaboration When You're Playing the Younger Version of a Character While Sharing Scenes with the Older Version

Maisy: "It was quick. What happened, I was filming for like two weeks when Aubrey was officially attached. So my younger Elliott was already kind of established. On anything else, if this was any other situation, I would have been meeting Aubrey — and she kind of had to meet me because I was filming.

So it was a quick thing, she came for like a week and we just went for it."

Megan: "She'd been watching dailies and studying Maisy a bit before."

Maisy: "And then when we met, I felt Aubrey staring and filming me with her eyes, and getting the mannerisms and physicality. I think that was probably more what we focused on.

And also just creating a friendship and a nice connection was probably the most important part, rather than mimicking each other. It felt more enjoyable."

Megan: "I remember Aubrey asking me 'do you want me to mimic her? How deep do you want me to go with this?' And I was like 'I feel like that's not the most important part of it. I'd rather we just build the chemistry and the rapport'.

And that was totally what I think was the main thing. We just spent the weekend together, talked through stuff."

Maisy: "100 percent."

Megan: "And it was just about building that chemistry — which, they're both genius actors, they can build chemistry so quickly. That's a skill that I think the best actors can do. And the two of them together  were just able to connect so quickly."

On Having Margot Robbie as a Producer, and How That Helped Shape the Film

Megan: "As we were saying, we love an Aussie. Our other producer, Bronte Payne at LuckyChap, is also Australian.

It happened really organically. I had a general meeting with the company, with Bronte, who had seen The Fallout — and she really loved the film, and she just wanted to sit and chat.

And she was the one, honestly, who was like 'do you have any other ideas?'. And I was like 'I mean, there's this one thing I'm thinking about'. And she was like 'we'd love to hear more about that. We think that's a great idea'.

Then she introduced me to the rest of people at the company, Tom [Ackerley, also one of LuckyChap's founders] and Margot and Josey [McNamara, another LuckyChap founder]. And they are just so — it's really hard to find good people in this industry who are really honest and smart and hardworking, and treat everybody, no matter if it's the star of the movie or the PA, they're just so consistent. And they're so grounded and down to earth, and there's a reason why they get so much repeat business with their directors. It's because it's genuine, and they're obviously very smart.

So they were incredibly helpful, not only helping me build the script, but every step of the way — they've just been so invaluable and so easygoing. And just lovely, lovely human beings.

I'm doing my next film with them, and I hope to work with them over and over again. They're incredible."

On Balancing Playing a Carefree 18-Year-Old with Their Whole Life Ahead of Them with Elliott Getting to Take Stock of Her Existence Decades Before Anyone Usually Expects To

Maisy: "Preparing-wise, I honestly read the script so many times. That was really my prep, just reading it. I didn't do too much, I didn't practice the deliveries."

Megan: "We just talked through the scenes."

Maisy: "We'd just talk it through. And on my own time, I had months before I went to film — but after I booked it, I enjoyed reading it so I would obsessively just read it and think about it a lot.

I really lived with the concept and with the message. I thought about it a lot. I think was my preparation."

Megan: "And you believed in it."

Maisy: "And I believed in it and I meant it. I really meant it. Everything that Elliott says, I ended up meaning on the day. Even if I was learning from her and trying to mean it, I did end up meaning it."

Megan: "Yeah."

Maisy: "And with an indie, with the director like you [talks to Megan], where you really like things to feel like you press record and you're just like watching people exist, there's only so much you can do for prep to keep it feeling natural and real and sparky."

My Old Ass opened in Australian cinemas on Thursday, September 26, 2024.
