1) Yes.
2) That was arguably one of the best adjustments the movie script makes. When seeing Rocky's ship, Book Grace is only worried that if its an Aliens situation, the mission to save Earth will fail. Movie Grace is also concerned about his own well being, which matches the bits you mentioned better.
In the books Grace knows that he must be a super brave and selfless person to sign up for a suicide mission, he hasn't remembered anything about how he got there at this point.

It seems like his decision at the end is a lot easier of a one to make knowing what he knows now about his chances of survival on the return trip itself. The long term sleep system is wholly unreliable and you’re on a heavily damaged ship versus helping out the real bro and saving his species as well.

Not only that, but Eridians live even further away from Earth. The trip back would be almost 50% more than his original trip. By the time he got back to Earth, probably 40+ years would have passed.

That being said, not sure what the long term health issues of living on their planet would be. Even in his biosphere, the gravity is much greater there (putting more strain on the body) and if a medical issue happened, the Eridians wouldn't be well versed to be able to help. Grace's ship might have all sorts of medical information I suppose

From my understanding, Grace is suffering from the double gravity on their planet, and also had malnutrition/scurvy/etc when he got there until they were able to synthesize food he could consume to get better. He's not going to last very long on their world as it is.

Two caveats:
1) I only saw it once, so I may have forgotten dialogue.
2) Again, there's a lot of stuff that was edited out of the movie. Movie Grace writes down something like "Always muscles?" on his whiteboard when he wakes up, and the one shot where he's sleeveless shows beefy arm muscles. The book explains that the Hail Mary traveled to Tau Ceti at 1.5Gs of ac/deceleration, and the med robot exercised them to compensate, but the movie skips over all that. That scene also shows movie Grace also has permanent burn scars over those arms - but in the final cut of the movie Rocky crawled back to his area on his own, so there's no movie explanation / reason for said burns.

In short, the final cut of the movie doesn't really detail Erid's specifics. When movie Grace opens Rocky's first message tube, the smell forces him to throw the tube in a chemical hood - book Erid's atmosphere is mostly methane at hundreds of degrees - but the movie doesn't go into why the contents of the tube are bad, nor are there any side effects when Rocky leaves his area as they leave Adrian. When movie Grace first goes up to the 'airlock' between ships, he's hit with 20 some atmospheres of pressure (which seems like it would do real damage to his ship even if it was human room temperature oxygen), but nothing is said about what type of gases those are.

On the gravity front, book Erid is ~2 times the gravity of earth, and book Grace points out arthritis is kicking in early between the gravity and everything they've gone through. The movie hand waves away gravity issues across the board, even having the ships spin around each other when the 'airlock' is being used to avoid filming those scenes in zero gravity... except the center of the centrifuge where the ships are connected wouldn't have any 'fake gravity' as a result!

Watched Project Hail Mary last night. It was decent, but not the amazing sci-fi film I was hoping for. Too silly and Disney-fied overall. I went in expecting harder sci-fi, but I did really appreciate the strong themes of friendship and loyalty..something a lot of recent movies have been missing.

Finally watched it last night, too.
Really great fucking movie. I agree it was exactly what we need more of: self-sacrifice, the greater good, loyalty, friendship, etc. I don't mind that it gave "make the kids happy" vibes at time because, honestly, it made me happy, too.


Side note:
I never read the book, so no idea if it comes up, but early on he "kills" one of the astrophage things. That's important wording because they acknowledge "life" by saying it that way... then immediately use it as a fuel source. One strike against the "morality" argument, I guess. Rocky's species made the same choice. kek

Did we watch the same movie? His girlfriend drugged and kidnapped him and stuck him on the ship.

We did watch the same movie.
I absolutely consider myself a morale person, and if it meant saving the entire universe I'd put my mother on that fucking ship if I believed she was the only person who could save the universe. Otherwise, and as pointed out in the movie, she'd die, anyhow.

*EDIT*
I should point out, however, that I'd be going, too.
Again, I haven't read the book, but it really bothered me that they knew there was other life in the universe and it never occurred to them (on Earth) that other lifeforms were being affected by the other starts dying. It occurred to me, immediately. And with that knowledge, they should have had an entire crew setup to deal with the actual First Contact side of things. Not to mention, if your mission is to solve a problem, don't assume you only need one scientist. I'd be sending people from every scientific focus.

In real life there's a very small chance the person you drug and press-gang into service is actually going to do what you need him to do. A ton of people would revolt at their agency being taken that way and refuse to help on principle, especially when they are totally isolated without contact at all.

We're starting from the place of "he's the guy for the job" but you can't know that, you absolutely can't predict how someone is going to respond under this kind of pressure, alone 11 light years from earth, with the very trip a death sentence.

I would think "motivation to do the job knowing full well you are going to die at the end of it" would be one of the primary qualifications since almost nobody would actually want to do it.

True, but you also don't send the janitor just because he volunteered. You HAVE to send someone with the capability. If they choose not to save the planet, then sure, you're fucked based on their decision... but not because you wasted time sending someone who couldn't have prevailed in the first place.

Logically makes sense, I'm just saying there had to be other qualified people. This guy didn't even do any astronaut training or anything. It's a movie plot point where they force the characters to do something stupid to advance the plot. In my world we call that bad writing.

The astrophage wasn't burned up as fuel - they used the astrophage as the propulsion. The astrophage "shitting" is how they propelled themselves at relativistic speeds. Plus it wasn't exactly endangered because it literally infected the entire local star cluster

I'm sure the thought occurred to them there was other planets with life, maybe even intelligent life, but they couldn't focus the mission on it. If you recall, the inside of Grace's ship had some golden plaques similar to the ones they put on the Voyager probes. There is absolutely no way they could have known an intelligent alien race capable of interstellar travel would be in Tau Ceti trying to solve the same problem, or at the very least, it would be such a low probability event that you can't hinge your mission on it. Although ignoring Earth and Eridians, would kind of suck if other star systems had intelligent life that wasn't capable of space travel. No one knows they are there and they'll all just get wiped out

It was obviously used up as fuel. Thus, the reason there could be no return trip until Rocky chose to give him more.
Unless I missed something?

As for the other point... I'm saying there are two simultaneous missions. One for sure, the other being other intelligent life showing up there to save their planet [a VERY real possibility]. The argument "WE are the proof of life in the universe" comes to mind. I'm saying they damn sure should have put some thought into it and had a plan.

The book goes into all of this, but:
Only 1 in 7000 people can survive the book coma; Grace happens to be one of them.
Book Grace is the one doing all the testing of their scientific equipment, and thus is familiar with everything*.
When the accident happens, the book Hail Mary is in an unstable orbit and either needs to leave immediately or face significant refueling issues.
The book timeline is much harsher, with anywhere from 25% to 50% of the population starving to death even if the Hail Mary finds a solution at Tau Ceti nearly immediately. Delaying the mission for X number of months to train someone isn't worth it when Grace is absolutely qualified on every point other than a willingness to go, and would result in tens? hundreds? of millions of additional deaths.

* I don't recall the movie conversation, but book Stratt makes it clear that this is intentional - since Grace has coma survivability, he's always her fallback science option and is trained as such, even if he doesn't realize it.
