Ryan Gosling’s Isolation on Project Hail Mary Led Him to Propose a Radical Directing Method

At first glance, Project Hail Mary—the latest sci-fi epic inspired by the work of The Martian author Andy Weir—appears remarkably precise. The narrative is a high-stakes puzzle: set in the near future, a solar pathogen begins dimming the sun, forcing a solitary scientist, Ryland Grace (Ryan Gosling), to journey to a distant star system in search of a solution. Along the way, he encounters and collaborates with an extraterrestrial being facing the exact same extinction-level threat to its own home world.

While the film’s core plot adheres closely to Weir’s acclaimed novel, Gosling explains that the production process under directors Phil Lord and Christopher Miller was surprisingly fluid. To prevent the lead actor from feeling isolated during a grueling shoot inside a claustrophobic spaceship set, the filmmakers utilized a technique more common in improv comedy. Gosling and his co-star Sandra Hüller (Anatomy of a Fall) shared with Polygon that they wore hidden earpieces, allowing Lord and Miller to whisper real-time prompts and alternative dialogue options directly into their ears during takes.

“It was actually Ryan’s idea,” Miller notes. “Since he spent so much time in scenes alone, he wanted us in his ear to pitch ideas so it felt less like a solo performance. Beyond that, we love throwing in curveballs mid-take. Whispering a direction is much more intimate and effective than shouting across a soundstage. It also keeps the other actors on their toes—we could tell Sandra to challenge him on a specific point to get a genuine, startled reaction.”

Lord mentions that this wireless communication extended to James Ortiz, the performer behind the alien character, Rocky. “We had a direct line to him, telling him to react to Ryan in specific ways just to see how the chemistry would evolve.”

“We’d tell him to keep messing with the measuring tape even if Ryan told him to stop,” Miller adds with a laugh. “Then we’d tell Ryan to make sure Rocky was reading the numbers correctly no matter what. It turned the scenes into these dynamic, lived-in games.”

“I needed that connection,” Gosling admits. “I spent about a hundred days isolated in those sets, tethered to wires and buried in a heavy spacesuit. Taking the suit off or dismantling the set just to discuss a note wasn’t practical. This system became a lifeline, but it also transformed into a unique shorthand with James and Rocky. It allowed for genuine ad-libbing.”

Hüller found the earbud method “liberating,” noting that she had used similar techniques in theater. “It shifts the weight of responsibility for a choice,” she explains. “You can choose which prompts to follow and which to ignore. It isn’t for every scene, but for finding spontaneity in a character, it can be incredibly effective.”

Gosling credits Ortiz for his deep understanding of Rocky, which allowed their improvised bond to feel authentic. “Because of James, we could have a real, breathing relationship. That spark of life is the magic of the film.”

According to Gosling, a significant portion of that unscripted energy made it into the final cut. Lord and Miller were specifically hunting for those moments of accidental brilliance. “That’s the secret sauce,” Gosling says. “The movie feels like it’s unfolding in real time because, in many ways, it was.”

Lord admits they were initially hesitant to adopt the earpiece strategy, fearing it might shatter the actor’s immersion.

“We were worried it would pull him out of the moment,” Lord says. “But Ryan is so present that he could process our notes and even the temp music we played for him—early sketches from composer Daniel Pemberton—and translate it all into a grounded performance. It was a revelation for us as directors.”

Project Hail Mary is currently in early-access screenings and arrives in theaters everywhere on March 20.
