Give Me the Backstory: Get to Know James Sweeney, the Writer-Director of “Twinless”

By Jessica Herndon 

One of the most exciting things about the Sundance Film Festival is having a front-row seat for the bright future of independent filmmaking. While we can learn a lot about the filmmakers from the 2025 Sundance Film Festival through the art that these storytellers share with us, there’s always more we can learn about them as people. We decided to get to the bottom of those artistic wells with our ongoing series: Give Me the Backstory!

James Sweeney is a Shakespeare fan. When asked about the biggest inspiration for his film Twinless, which he wrote, directed, and stars in, the multihyphenate recites the famous line said by witches in the playwright’s Macbeth: “Double, double toil and Trouble.” The rhyme, which can have double meanings and is emblematic of the chaos and destruction the witches bring, perfectly compares to Sweeney’s film, premiering at the 2025 Sundance Film Festival in the U.S. Dramatic Competition.

Twinless is a sharp, shocking, dark comedy about grief, friendship, and the search for connection. When two men, played by Sweeney and Dylan O’Brien, meet in a support group for individuals who’ve lost their twin, they develop an unexpected friendship that teeters between healing and unhealthy codependency. 

Witty, emotionally raw, and a bit twisted, Sweeney’s Fest debut is also incredibly fun. “Storytelling is humanity’s coping mechanism for the mysteries and challenges of life,” says Sweeney. “Film can be a guide, a relief, or a sly dose of empathy.”

Below, Sweeney chats about why O’Brien was the perfect addition to the film’s cast and why he feels connected to Sofia Coppola. He also offers words of wisdom for other filmmakers.

Films are lasting artistic legacies. What do you want yours to say?

Forgiveness is radical empathy.

Describe who you want this film to reach.

In order of importance: 1) identical twins, 2) fraternal twins, 3) everyone else

Tell us an anecdote about casting or working with your actors.

Okay, deep cut time. I initially thought of Dylan O’Brien for Twinless after his scene re-creation from The Social Network, with Sarah Ramos, went viral in 2020. I had most recently adored his performance in the pilot episode of the YouTube series Weird City, cast by my friend Jess. I sent her a note; she loved the idea. Casting against type, or so I presumed. When Dylan and I first met, he dispelled my preconceptions and took complete emotional ownership [of] the character. Looking back now, it always had to be him.

What was your favorite part of making Twinless? Memories from the process?

I loved living in Portland. So many memories. One that comes to mind — our key grip, Bruce, was unavailable for our first few days [of] filming in December because he moonlights as Santa Claus. I was in the middle of a take when fully dressed Santa, straight from the mall, climbed into bed beside me. He asked what I wanted for Christmas this year. It was already happening.

What was a big challenge you faced while making Twinless?

In the last week of prep, Portland got hit by the second-worst snowstorm in its recorded history. We weren’t allowed to be on the roads, and since we didn’t have all of our locations locked, it had a snowball effect — sorry, couldn’t help it — on our entire shooting schedule.

Why does this story need to be told now?

I’ve been wanting to tell this story for a long, long time, so my honest answer is financing. My cheeky answer is: There has been a statistically significant increase in twin births worldwide since the ’80s, so there are also more twins dying now than ever before.

Tell us why and how you got into filmmaking.

Theater was my first kink, television my second. I grew up in a small town in Alaska with one local cinema, so I didn’t really experiment with filmmaking until college. They all scratch my itch to idle in my imagination.

Why is filmmaking important to you? Why is it important to the world?

Sofia Coppola once said directing “is the only time you get to have the world exactly how you want it.” I resonate with that — balancing how it is with how it could be.

If you weren’t a filmmaker, what would you be doing?

Someone recently told me that I answered their questions like a lawyer: Not intentionally evasive, but I leave room for plausible deniability. 

What is something that all filmmakers should keep in mind in order to become better cinematic storytellers?

Kindness is free, and music licenses are expensive.

Who are your creative heroes?

I try not to have heroes anymore.

One thing people don’t know about me is _____.

I cannot whistle.

Which of your personal characteristics contributes most to your success as a storyteller?

Counterintuitively, my decision anxiety.

Tell us about your history with Sundance Institute. When was the first time you engaged with us? Why did you want your film to premiere with us?

My history with Sundance has been exclusively rejections. I applied to the Screenwriters Lab eight years ago with Twinless. I wanted to premiere at Cannes, but I was overruled. (Kidding! Now I’ve caught the whale muahahaha.)

Who was the first person you told when you learned you got into the Sundance Film Festival?

Dylan [O’Brien].

What’s your favorite film that has come from the Sundance Institute or Festival?

Favorite is a strong word, but sex, lies, and videotape was formative.
