The minute someone told me that Project Hail Mary feels like an old-school ’80s movie, I knew it had to go on my watch list ASAP. If your kids love space, adventure, or Ryan Gosling, you’ve probably seen Project Hail Mary trending as a must-see movie in theaters right now. But is Project Hail Mary OK for kids to watch?
My 9-year-old and I love going to the movies together, and this is one of the biggest movies coming out this year. But could some scenes be too intense for his age demo? I dug deep into how appropriate the film really is for kids. Below, I’m breaking down what parents should know about the best viewing age, scary moments, and what to watch out for if you take your kiddo to the theater to catch this new flick.

What Is Project Hail Mary About?
Based on the bestselling novel by Andy Weir, Project Hail Mary is a classic sci-fi adventure. Weir previously wrote The Martian—which was then turned into a 2015 movie starring Matt Damon—and Project Hail Mary is a similar story mixing comedy and adventure. I’ve even heard it described as this generation’s E.T.
The Project Hail Mary book-to-movie adaptation follows science teacher Ryland Grace (played by Ken, uh, I mean Ryan Gosling) as he wakes up from a medically-induced coma in 2032, light-years from home and alone on a spaceship. He can’t remember who he is or why he’s there. He quickly realizes he’s on a mission to save Earth. Here’s where the E.T. comparison comes in: he befriends the only other life-form around, a cute alien named Rocky.
Quick Facts About the Project Hail Mary Movie
- Rating: PG-13
- Rated For: Some peril, mild language, and sci-fi tension
- Genre: Sci-fi, Adventure
- Length: 2 hours, 37 minutes
- Recommended Age: 10+, depending on sensitivity

Should You Let Your Kids Watch Project Hail Mary?
With a PG-13 rating (for mild language and some sci-fi related danger), this adventure movie may best be suited for an older elementary-aged kid. If you have a 6-year-old who’s obsessed with space exploration and all-things science, it may be too intense for them. All kids are different, however, so I’d recommend watching Project Hail Mary on your own first if you plan to watch with a kid under age 10.
Is Project Hail Mary Scary?
Again, this really depends on the person. What might be scary or disturbing for me wouldn’t frighten my kid. The film includes tension and suspense and some serious life-or-death stakes (it does take place in space, after all). That might make kids who are naturally nervous even more anxious, so definitely take that into account.
Project Hail Mary movie scenes that may be intense for kids:
- Space peril: Life-or-death situations in a confined setting
- Suspenseful problem-solving: High-pressure moments where failure has big consequences
- Isolation: The main character is alone for much of the film
- Emotional stakes: The fate of Earth and humanity
