From Sally Field to Lewis Pullman, here are the main Remarkably Bright Creatures cast members. 

Sally Field as Tova

 There are few performers who can move effortlessly between comedy, drama and pure emotional truth quite like Sally Field—and that’s exactly what she brings to Remarkably Bright Creatures.

An Oscar-winning actress whose career stretches from television favorites like Gidget (1965–1966) and The Flying Nun (1967–1970) to acclaimed film performances in Steel Magnolias (1989), Forrest Gump (1994) and Lincoln (2012), Field has long had a gift for grounding even the most heightened material in something real. Along the way, she’s also left her mark on projects as varied as Mrs. Doubtfire (1993), ER (2000–2006), Brothers & Sisters (2006–2011) and The Amazing Spider-Man films (2012, 2014).

In Remarkably Bright Creatures, she takes on the role of Tova, an elderly cleaning woman at a local aquarium—a character whose quiet routine masks a deeper emotional journey. It’s the kind of role that plays directly to Field’s strengths: layered, compassionate and filled with the kind of lived-in authenticity that has defined her work for decades, 

“The whole book is surprising and life-affirming, and it’s an homage to life, to creatures, and the connection that human beings have to creatures,” Field told People. “We worked on it relentlessly just to get that screenplay. Even when we were shooting we were constantly noodling and fixing and letting it breathe and have its own existence outside of the book. It was a long journey.”

Field is 79 years old and has three children. 

Lewis Pullman as Cameron

Lewis Pullman may be the son of Bill Pullman, but in recent years he’s been steadily carving out a screen presence all his own. With roles in films like Battle of the Sexes (2017) and Top Gun: Maverick (2022), along with television work in Outer Range (2022–2024) and Lessons in Chemistry (2023), Pullman has shown a knack for characters who feel grounded and relatable, even in heightened circumstances. His appearance in Thunderbolts* (2025) further signaled a career on the rise.

In Remarkably Bright Creatures, he plays Cameron, Tova’s long-lost grandson. It’s a part that plays directly into his strengths, allowing him to bring a sense of vulnerability and quiet intensity to a character searching for where he belongs.

“I had read with a couple of other young actors, but the minute Lewis walked in, the minute I saw him, I just knew, ‘Here he is,’” Field told People. “Not only is he just a dazzlingly wonderful actor and funny and talented in every way … to me, he just was this character. We just started improvising instantly and having fun with it and laughing. And we were almost uncontainable. He’s just so easy to be with and work with.” 

Pullman is 33 years old and originally from Los Angeles, California. 

Alfred Molina as Marcellus 

Alfred Molina has spent decades building a truly versatile career in both film and television, moving effortlessly between drama, comedy and larger-than-life characters. From his early appearance in Raiders of the Lost Ark (1981) to memorable turns in Boogie Nights (1997), Magnolia (1999) and Frida (2002), the actor has consistently brought depth and dimension to every role he takes on.

He’s equally at home in mainstream fare—whether voicing characters in animated hits like Monsters University (2013) and Ralph Breaks the Internet (2018), or stepping into the Marvel universe as Doctor Octopus in Spider-Man 2 (2004) and Spider-Man: No Way Home (2021). On television, his work has ranged from sitcoms like Ladies Man (1999–2001) to dramas such as Law & Order: LA (2010–2011), showcasing a truly incredible range.

In Remarkably Bright Creatures, Molina lends his voice to Marcellus, an octopus living in the aquarium where Tova works. It’s a role that may be unexpected, but one that seems tailor-made for Molina’s ability to infuse even the most unconventional characters with intelligence and personality.

Molina is 71 years old and originally from Paddington, London, United Kingdom. He has one daughter. 

Colm Meaney as Ethan

Colm Meaney has long been one of those actors whose presence immediately lends credibility to a project. With a career that spans decades, he’s become a familiar face across both television and film.

Many viewers know him best from his time in the Star Trek universe—first on Star Trek: The Next Generation (1987–1994) and then on Star Trek: Deep Space Nine (1993–1999) as Chief O’Brien—but his work extends far beyond that. From films like Under Siege (1992) and Con Air (1997) to later projects such as Layer Cake (2004), Stargate: Atlantis (2004–2006) and Hell on Wheels (2011–2016), Meaney has built a reputation for portraying characters who feel lived-in and real. In Remarkably Bright Creatures, he plays Ethan, a friend of Tova’s.

Meaney is 71 years old and originally from Dublin, Ireland. He has two children.
