I cannot overstate how much I love the Project Hail Mary movie- but there was a concept change from the book to film that I felt stuck out a little errantly.
First- yes; they have to sacrifice a lot between the book and the movie, I make peace with this (most of the time). However, in PHM, one of the things that felt too important to diverge from was how strikingly mirrored Grace was to Rocky. Not as friends, but as individuals. Simplistically, they were psychological and intellectual reflections of each other.
At the point in the storyline where the two species learned to communicate, both characters had already passed the point of mission status: desperation. It was dire circumstances with different forms of helplessness, despite equal intent.
Rocky and Grace both:
-left with a crew and were now alone. Neither one knew why.
-had a specialized skillset that made them uniquely qualified to work the known problem- it just wasn’t enough.
-welcomed help of any kind (this fact is insane. trying to imagine another human being in Ryland’s place does not work. It had to be him. We can assume it’s the same for Rocky)
-weren’t giving up on the mission*
-weren’t giving up on each other
When the communication barrier was no longer an issue, it became a tennis match of science, math, physics, chemistry, etc. Rocky was just as science smart as Grace, and they locked together seamlessly in order to work each problem as they came. It wasn’t perfect, and their ideas didn’t always work, but it wasn’t The Scientist and The Engineer. Their individual skills were bound only by the physical limitations of their separate environments. Knowledge was soaked up on both sides, contributing equally to every problem.
The point I guess I’m making is that I could have done without the scenes where one (or both) of them is made to look incompetent for the sake of the audience. ‘I have done this for you cause you did that for me.’ Even when irritated with each other, their contributions were more or less balanced to the cause.
Rocky saves Grace, Grace saves Rocky. They both save Earth and Erid together.
That’s it- that’s the movie.
*Grace gave up over and over in the movie, especially at the beginning, which was a critical time in the book to learn every inch of the ship and attempt to regain what he’d lost of himself.
Some of the goofiness was fine, that was in character and that’s fun to watch, but by going over the top with the terrified and blundering human act, Grace’s bravery came off as clumsy resignation. The man was writing math equations on his skin before he could find paper (let alone get to any computer controls). He was surprised to discover that he was good at spacewalking. There was a rooted determination to succeed without even knowing how he’d gotten there. Lacking these traits lessens the shock reveal that Grace woke up as another person. He hadn’t been brave, he hadn’t even consented to be there in the first place. And we feel this. It hurts so much because he’d worked and wept and sacrificed himself right from the start, shipped across the universe without help, without his name, on behalf of the planet that had betrayed him.
