Loved Project Hail Mary? These sci-fi movies hit just as hard

Project Hail Mary has quickly cemented itself as another blockbuster adaptation of Andy Weir’s work, and honestly, it’s not hard to see why. It delivers that rare mix of stunning visuals, sharp science, gripping isolation, and an emotional payoff that actually sticks with you.

After watching it last weekend, I went looking for movies like Project Hail Mary that could recreate that feeling and quickly realized most sci-fi recommendations miss the point. So I put together a list of films that don’t just look similar, but actually deliver that same mix of smart storytelling and emotional impact.

What made Project Hail Mary a global blockbuster

Inspired by Andy Weir’s immensely popular book, the movie came with high expectations. And instead of playing it safe, it doubled down on what made the book special: science as storytelling.

Based on its performance at the global box office, the movie is already in blockbuster territory. With a gross of about $638 million worldwide, it managed to exceed everyone’s expectations, even beating “The Martian” to make it Weir’s biggest movie adaptation yet.

But what really stands out to me is why it worked. This is not an in-your-face, action-heavy blockbuster. The movie became the talk of the town because it:

Turns problem-solving into tension and somehow makes equations feel like action scenes
Weaponizes isolation—one man, no backup, no shortcuts
Builds emotional stakes quietly, then hits you when you’re not ready
And most importantly, proves sci-fi can be smart and deeply human at the same time

That mix is rare, and that’s exactly why finding similar sci-fi movies like Project Hail Mary is harder than it sounds.

Top 6 movies that actually capture that same feeling

If you are searching for what to watch after Project Hail Mary, here’s my list of top contenders. The best part is that most movies are available on Apple TV, Amazon Prime Video, Netflix, and Hulu. So, subscribers can start watching right away.

1. Interstellar

Cast: Matthew McConaughey, Anne Hathaway, Jessica Chastain, and more
Director: Christopher Nolan
IMDb Rating: 8.7/10
Release Date: 2014

In my opinion, this film doesn’t call for an introduction since most sci-fi fans would have already seen it. However, just in case, allow me to give you a brief summary. This is about a group of astronauts who travel through a wormhole in order to rescue humanity.

Underneath the science theme, it’s really about time, love, and impossible choices. The story is ambitious, emotional, and sometimes overwhelming, but it hit me harder than most films in the genre.

2. The Martian

Cast: Matt Damon, Jessica Chastain, Jeff Daniels, and more
Director: Ridley Scott
IMDb Rating: 8.0/10
Release Date: 2015

This is the obvious pick, and honestly, it deserves to be. If PHM had a cinematic sibling, it’s The Martian. Adapted from Andy Weir’s novel, the movie shows what happens when science becomes survival, and somehow, entertainment.

Stranded alone on Mars, an astronaut has to science the hell out of every problem just to stay alive. But here’s the difference I noticed after rewatching: The Martian is more optimistic. PHM is more emotional.

3. Arrival

Cast: Amy Adams, Jeremy Renner, Forest Whitaker, and more
Director: Denis Villeneuve
IMDb Rating: 7.9/10
Release Date: 2016

Adapted from the Story of Your Life novel, Arrival isn’t your typical alien-contact story; it’s quiet and deliberate. When mysterious spacecraft land on Earth, a linguist is brought in to decode their language, turning communication itself into the central conflict.

The thing that impressed me the most is how easily science merges with emotions in the film, like the relationship between Ryland Grace and Rocky in Project Hail Mary.

4. Moon

Cast: Sam Rockwell, Kevin Spacey, Dominique McElligott, and more
Director: Duncan Jones
IMDb Rating: 7.8/10
Release Date: 2009

If the Project Hail Mary left you feeling lonely, the film Moon amplifies those emotions. Just one guy at the moon’s mining facility, realizing something’s not quite right about the situation. The twists and turns made the film more psychological rather than science fiction.

What stayed with me is how it turns isolation into tension and identity into the real mystery. You will also experience how corporate greed turns human beings into tools.

5. Gravity

Cast: Sandra Bullock, George Clooney, Ed Harris, and more
Director: Alfonso Cuarón
IMDb Rating: 7.7/10
Release Date: 2013

Gravity is pure survival stripped down to its most intense form. When a routine space mission goes catastrophically wrong, an astronaut is left alone, fighting to stay alive with nothing but her training and instincts.

If you loved the visuals of Project Hail Mary, this movie will not disappoint you. What I felt watching it was a never-ending tension and horror of being alone in space. It’s relentless, immersive, and makes isolation feel terrifyingly real.

6. Ad Astra

Cast: Brad Pitt, Tommy Lee Jones, Ruth Negga, and more
Director: James Gray
IMDb Rating: 6.5/10
Release Date: 2019

Unlike what it was promoted as, Ad Astra is not about action in space. It follows an astronaut traveling to the edge of the solar system to find his missing father, but the real journey is internal.

I didn’t fully appreciate Ad Astra on my first watch, but on revisiting, its slow, introspective tone really landed the same themes of connection and life as Project Hail Mary. It’s the kind of emotional sci-fi that stays with you afterward.
