Why Ryan Gosling’s Project Hail Mary Tones Down 1 Element Of Andy Weir’s Sci-Fi Novel Explained

by

The movie adaptation of Ryan Gosling’s Project Hail Mary is being praised for staying true to Andy Weir’s original book, though there are a few differences. Be aware that minor plot details might be revealed if you haven’t read the book or seen the film yet!

The movie, based on a 2021 science fiction novel, stars Ryan Gosling as Ryland Grace. He wakes up on a spaceship far from Earth with no memory of who he is. As his memories return, he realizes he’s a scientist sent to figure out why the sun is fading. With the help of an unexpected friend, Ryland must find a way home and save Earth.

Ryan Gosling, who worked on the film as both a producer and actor for several years, is joined by a cast including Sandra Hüller, James Ortiz, Lionel Boyce, Ken Leung, and Milana Vayntrub. Drew Goddard, the writer of the acclaimed film The Martian, wrote the screenplay for Project Hail Mary. Directing the sci-fi adventure are Phil Lord and Chris Miller, the team behind 22 Jump Street, in their first live-action feature since that film.

The new movie Project Hail Mary, released on March 20th, is receiving rave reviews from both critics and audiences. It currently has a 95% “Certified Fresh” rating on Rotten Tomatoes from critics and a 97% audience score. The film is also a box office hit, earning $12 million on its opening Thursday – the biggest of 2026 – and is predicted to make up to $65 million domestically during its first weekend, which would be a record for Amazon MGM Studios.

Before the movie came out, Liam Crowley from ScreenRant spoke with Ryan Gosling, Drew Goddard, Andy Weir, and Phil Lord & Chris Miller about Project Hail Mary. The film mostly follows the book, but one thing that was changed was how much they talked about Erid – the home planet of Ryland’s alien friend Rocky – and the Eridians, the other beings who live there.

Regarding the change from the original novel, Goddard explained that while the Eridians still appear in Project Hail Mary, they aren’t discussed as often. This is because, in Weir’s book, Ryland mostly thinks about them rather than talking about them aloud. For the movie, Goddard said they only discuss the Eridians when Ryland and Rocky specifically talk about the planet.

Drew Goddard explained that while elements from the book are present, they aren’t as prominent because there wasn’t a natural way for the character Rocky to prompt Ryland to share everything. He credited Ryan Gosling with consistently focusing on what Ryland would realistically say in each scene, rather than just delivering necessary plot information. This approach significantly shaped the final film.

Gosling Was At The Top Of Weir’s List To Play Project Hail Mary’s Ryland

ScreenRant commented that when they heard I was cast, they thought it didn’t make sense – that I was too likable for the role. But after seeing the film, they said no one else could have played Ryland Grace. I was asked how I managed to portray the character’s awkwardness.

That’s a lovely way to start, thank you. Honestly, I’m terrible with space, and so is the character I played. Neither of us are astronauts! I really connected with his fear of what lay ahead. I found we had a lot in common, which is probably why people connect with the story and the character so much. He’s not your typical hero – he’s not strong and silent, or traditionally brave. He’d rather avoid a problem than face it, and he needs to learn to have faith in himself. I think that’s something a lot of us can understand.

ScreenRant noted that you often play very reserved characters, like Sebastian in La La Land and Officer K in Blade Runner 2049, expressing a lot through facial expressions. They asked what it was like to play a more talkative role, where quick dialogue and witty remarks were key to showing the character’s emotions, especially during scenes where you were essentially performing alone.

I’m a big fan of Andy’s work, and that’s why I really wanted Chris and Phil to direct this film. They were the right people for the job because humor is so crucial, especially when dealing with complex scientific ideas. It makes the science easier to understand, and it balances out the emotional weight of the story. During filming, things were constantly going wrong – we were working with a very demanding puppet named Rocky, who had his own team of puppeteers, ‘The Rocketeers,’ dressed as ninjas! Having someone like James Ortiz, one of the puppeteers, who could find the funny side of these challenges and incorporate them into the scenes really added to the film’s magic and made it feel more spontaneous.

The trailer offered a quick look at Adrian, and that scene reminded me of the emotional impact of the docking sequence in Interstellar, but even more intense. When reading that part in the book, did you have a sense of how powerfully it would come across on film?

Chris Miller says the book is a real rollercoaster – thrilling, funny, and even moving. They wanted the film adaptation to be visually unique and create a powerfully tense atmosphere through sound, imagery, and music, leaving the audience breathless.

ScreenRant asked about working with Andy Weir, the author of The Martian, since I wrote the screenplay for that film. They were curious about what it’s like to collaborate with him – how we take his written story and adapt it into a script for a movie.

Drew Goddard and Andy Weir share a deep appreciation for each other’s work, which was the foundation of their collaboration. Having successfully adapted ‘The Martian’ together, they’ve built a strong level of trust. Goddard felt this new adaptation was more challenging because the source material was a more complex and ambitious book. Initially, he was worried about translating it to film, finding many elements difficult to adapt for the screen. However, as he continued reading, he became increasingly captivated by the story. Ultimately, he realized the project would be difficult, but his passion for the book compelled him to try.

ScreenRant asked if Ryan Gosling was always the first choice for the role of Ryland Grace. They wanted to know if there was a particular performance of his that convinced them he was perfect for the part.

I don’t really have much say in casting decisions, so people shouldn’t read too much into who I preferred. I was thrilled with Ryan Gosling – he was perfect! He would have been my first choice, but ultimately, the studio made the final decision. Luckily, he was also interested, which made everything work out great.

You know, I was really wondering about the visual choices in the film. Specifically, things like how they imagined Rocky and Adrian as planets – did the director actually get involved with the concept art and visual effects to shape those ideas?

Andy Weir explained that he wasn’t heavily involved in the visual aspects of the film adaptation. He doesn’t visualize things strongly when he writes; he imagines characters as vague shapes rather than detailed appearances. He’d figured out how Rocky functioned, but not what he looked like. He happily left the visual design to the professionals, and when they presented their work, it immediately clicked for him. Because he hadn’t formed his own strong mental images, he didn’t experience any disconnect between his vision and what was created on screen. It simply was Rocky and Ryland.
