I was in the library the weekend before last when I spotted something on the shelf of recently-returned books. Project Hail Mary by Andy Weir.

I knew the film adaptation was coming out later that week. Ideally, I’d like to read the book before seeing the film. It would be a race against time! The film would be out in days, and the book is over 450 pages long. Could this nerdy white guy rise to challenge and overcome the odds?

As it turned out, it wasn’t all that arduous. Project Hail Mary is a real page-turner, just like Andy Weir’s previous book, The Martian.

But his books are worryingly regressive. The so-called golden age of science fiction featured plenty of plucky white science guys saving the day with their brainpower in books written by white science guys. Andy Weir’s books have a similar outlook.

On the other hand, they’re undeniably fun. And who knows? Maybe his next book will feature a protaganist that isn’t an aw-shucks white guy.

(Update: multiple people have pointed out that I completely missed that Andy Weir’s other book, Artemis, features a refreshingly different kind of protaganist—phew!)

Project Hail Mary is packed with plenty of plausible-sounding science. Perhaps too much. After a while it felt like elements were being added to the story to showcase the author’s smarts rather than to propel the plot.

Over all, the book is good entertaining fun but a bit baggy and could’ve been edited down somewhat.

I was interested to see how the film would translate the science from the written page to the screen. Very commendably, as it turns out.

The film does a great job of avoiding expositional blackboard sequences or explanatory dialogue. Wherever possible, it shows rather than tells. It helps that it doesn’t underestimate what the audience can handle.

Above all, it’s entertaining. Popcorn was invented for this kind of film. Ryan Gosling does his usual entertaining shtick, though I kept thinking that Sam Rockwell would’ve really delivered the goods.

The film trims the book down to its essentials. I didn’t miss any of the elements they chose to cut. I did spot one glaring mistake, but that was continuity error rather than anything to do with the science.

Project Hail Mary the film is better than Project Hail Mary the book. Go see it. And if it leaves you wishing for more, then you can always read the book.
