The 2017 science fiction romance The Space Between Us captivated audiences with its unique premise: the first human born on Mars traveling to Earth for the very first time. While the sweeping landscapes of the Red Planet and the scenic vistas of the American Southwest provided a stunning backdrop, the true heart of the film lies in its ensemble. The cast of The Space Between Us features a blend of rising young stars and legendary Hollywood veterans, each bringing depth to a story about connection, isolation, and what it means to be human.

The Core Duo Leading the Cast of The Space Between Us

At the center of this interplanetary adventure are two young actors who had to carry the emotional weight of a long-distance relationship spanning millions of miles.

Asa Butterfield as Gardner Elliot

Asa Butterfield portrays Gardner Elliot, the curious and highly intelligent teenager born on a Mars colony. By the time Butterfield took on this role, he was already a seasoned actor known for his work in The Boy in the Striped Pyjamas and Hugo. However, Gardner Elliot presented a unique physical and emotional challenge.

In the film, Gardner has spent his entire life in the low-gravity environment of Mars. Butterfield’s performance is notable for how he incorporates this into his movement. When Gardner first arrives on Earth, his gait is slightly awkward, reflecting a body struggling against a gravity it was never built to endure. His portrayal captures a sense of wide-eyed wonder; everything from the feeling of rain to the taste of a hamburger is a revelation. Butterfield balances Gardner’s genius-level intellect with a social innocence that makes his quest to find his father deeply sympathetic.

Britt Robertson as Tulsa

Opposite Butterfield is Britt Robertson, who plays Tulsa, a street-smart and fiercely independent foster child living in Colorado. Robertson, known for her roles in Tomorrowland and The Longest Ride, provides the perfect grounding force for the film.

Tulsa is the "Earthly" anchor to Gardner's "Martian" perspective. While Gardner sees the beauty in everything, Tulsa is cynical, shaped by a life of being bounced around the foster care system. The chemistry between Robertson and Butterfield is the engine of the movie. Robertson brings a tough exterior to Tulsa, but as the story progresses, she masterfully reveals the character’s vulnerability and her own longing for a place to belong. Her ability to portray a teenager who is both a rebel and a protector is a testament to her range as an actress.

The Visionaries and Guardians in the Cast

The supporting cast of The Space Between Us includes Academy Award winners and celebrated character actors who provide the institutional and emotional framework for Gardner’s journey.

Gary Oldman as Nathaniel Shepherd

Legendary actor Gary Oldman takes on the role of Nathaniel Shepherd, the visionary billionaire and founder of Genesis, the company responsible for the Mars colony. Shepherd is a complex character; he is the "father" of the mission but is also haunted by the secrets he has kept for sixteen years.

Oldman brings his signature intensity to the role. Shepherd is a man driven by ambition but crippled by the fear of a public relations disaster and the health of the boy he helped create. Throughout the film, Oldman’s performance shifts from a powerful corporate leader to a desperate man seeking redemption. His character’s arc is one of the most significant in the film, providing a bridge between the cold technology of space travel and the messy reality of human emotion.

Carla Gugino as Kendra Wyndham

Carla Gugino plays Kendra Wyndham, an astronaut who serves as a surrogate mother to Gardner on Mars. Gugino, a versatile actress known for Spy Kids and The Haunting of Hill House, brings warmth and maternal instinct to a character living in a sterile, scientific environment.

Kendra is the person who understands Gardner better than anyone else. Her struggle is one of the most relatable aspects of the film; she wants Gardner to experience the world he dreams of, but she is terrified that the very world he loves will kill him. Gugino plays this internal conflict with grace, making Kendra’s eventual decisions some of the most moving moments in the movie.

Vital Supporting Characters and Their Contributions

The ensemble is rounded out by actors who play crucial roles in both the mission on Mars and the search on Earth.

B. D. Wong as Tom Chen

B. D. Wong portrays Tom Chen, the director of the Genesis program and Nathaniel Shepherd’s pragmatic counterpart. Wong, widely recognized for his roles in Jurassic Park and Law & Order: Special Victims Unit, brings a necessary sense of grounded authority to the film. While Shepherd is the dreamer, Chen is the one dealing with the logistical and ethical realities of keeping a human hidden on Mars. His performance provides a sharp contrast to the more emotional beats of the story, representing the bureaucratic pressures that often clash with individual lives.

Janet Montgomery as Sarah Elliot

Janet Montgomery plays a brief but pivotal role as Sarah Elliot, Gardner’s mother. As the astronaut who discovers she is pregnant during the flight to Mars, her performance sets the entire plot in motion. Though her screen time is limited, the impact of her character is felt throughout every scene, as Gardner’s entire identity is shaped by the mystery of her life and her tragic death during childbirth.

Gil Birmingham as Shaman Neka

Gil Birmingham appears as Shaman Neka, a man who holds a key piece of the puzzle regarding Gardner’s father. Birmingham, known for his work in Twilight and Yellowstone, adds a layer of spiritual and cultural depth to the film’s second act. His character provides a moment of stillness and reflection during the frantic road trip across the American West.

The Surprising Guest Stars and Cameos

The Space Between Us also utilized then-rising social media personalities to appeal to a younger demographic, a move that reflected the film's themes of digital connection.

Logan Paul as Roger

In a brief appearance, Logan Paul plays Roger, a "buff college kid" whom Gardner and Tulsa encounter during their travels. While his role is minor, it serves as a snapshot of the cultural landscape at the time of the film’s production in 2015-2016, highlighting the intersection of traditional cinema and the burgeoning world of internet influencers.

Adande Thorne (Swoozie) as Scott Hubbard

Another notable cameo is Adande Thorne, better known by his YouTube handle "Swoozie." He plays Scott Hubbard, further emphasizing the film’s attempt to bridge the gap between various forms of modern celebrity.

Behind the Scenes: Casting and Direction

The cast of The Space Between Us was carefully selected by director Peter Chelsom and his casting team to ensure a mix of gravitas and youthful energy. Chelsom, known for directing films like Serendipity and Hector and the Search for Happiness, sought to create a "humanistic sci-fi" movie.

The Age Gap and Chemistry

One of the interesting pieces of trivia regarding the cast is the age difference between the lead actors. In the film, Gardner and Tulsa are roughly the same age (16-17). However, during filming, Britt Robertson was significantly older than Asa Butterfield. Despite this seven-year gap in real life, their on-screen chemistry was praised for its sincerity. The actors spent time together during pre-production to build a rapport that felt natural, moving from a digital-only friendship to a high-stakes physical adventure.

Physical Training for the Role

For Asa Butterfield, the role required more than just line memorization. He had to work with trainers to understand how a person raised in 38% of Earth’s gravity would move. This involved wearing weighted vests and practicing a specific type of heavy-footed walking. The rest of the "Mars" cast, including Carla Gugino, also had to convey the physical toll of long-term space habitation, adding a layer of authenticity to the production.

Why the Casting of The Space Between Us Matters

The success of a "Young Adult" sci-fi film often hinges on whether the audience believes in the central relationship. By casting Asa Butterfield, the production secured an actor who could project intelligence without losing vulnerability. By casting Britt Robertson, they secured a lead who could ground the fantastical elements of the story in emotional reality.

The inclusion of Gary Oldman elevated the film’s stakes. His presence transformed Nathaniel Shepherd from a generic "CEO" character into a flawed, tragic figure. This balance of veteran talent and young stars allowed the film to explore themes that resonate across generations: the search for a father, the fear of the unknown, and the universal need for a home.

Since the film's release in 2017, many of the cast members have gone on to achieve even greater success in the industry.

  • Asa Butterfield became a global household name as Otis Milburn in the hit series Sex Education. His work in that series further showcased his ability to play socially awkward yet deeply empathetic characters, a trait he perfected in The Space Between Us.
