I think the Martian was adapted well from book to movie, so I have hope for this one. That said, compressing the entire story into a theatre runtime is tricky: I think it would be a win if only half of the character and relationship growth of the two ship bound protagonists comes through in the adaptation (because it was sooo good in the book!)

The Martian was well adapted as the story has an attention to scientific details, can’t say that for Project Hail Mary

True - but I think that might make the adaptation to a movie easier, not harder.

Like GP said, I think the trick to this book is in the relationship between the 2 main characters, so hopefully they nail that. Judging by the trailer they made it all quite humorous.

I know they have to peak interest, but man, so many spoilers in the 2 trailers. They look amazing, clearing a huge budget and I hope a solid adaptation… sad for people that don’t know the story to miss out on the reveals.

Andy Weir is a producer on this one. The trailer looks good (with spoilers)

That Oasis tune in the 2nd trailer already ruined everything for me.

The audiobook narrated by Ray Porter is also really good.

In fact, it's so good that it sets a really good example of what an enjoyable experience listening to an audiobook can be.
