    The Project Hail Mary Film Could Anger Book Fans
    But The Changes Are Justified
    ------------------------------------------------
    The many differences between the Project Hail Mary film and the
    book are causing some friction. The sci-fi adventure blockbuster,
    starring Ryan Gosling and directed by Phil Lord and Christopher
    Miller, is based on Andy Weir's 2021 novel of the same name.
    Including the $3 million price for acquiring the rights to the
    novel, Amazon MGM Studios has spent nearly $250 million on the
    film's production (though that was cut to around $200 million
    after tax credits). Even so, like any adaptation of a popular
    book to the silver screen, many scenes were cut, some storylines
    were altered, and a few elements were added. That said, unlike
    the 2015 movie The Martian that is based on another novel by Weir,
    the author is one of the producers of the film and was a part of
    the approval process for any changes the movie made.


    Changes to the Project Hail Mary book were inevitable
    From the outset, it would be clear by anyone who has read "Project
    Hail Mary" that any film adaptation of the nearly 500-page novel
    would need to be revised or edited out. The original story, which
    follows science teacher Ryland Grace on a space mission to save
    the Earth after it's discovered that the sun is effectively dying
    out due to an energy-sucking organism dubbed the Astrophage, is
    full of thorough, grounded scientific explanations and a lot of
    internal dialogue from Grace himself. While both of these traits
    are hallmarks of Weir's writing, these are difficult to translate
    through the visual medium of a film.

    Meanwhile, directors Lord and Miller are known for adding a slice
    of comedy to their productions, which include 21 Jump Street,
    Spider-Man: Across the Spider-Verse, and The Lego Movie. The same
    goes for screenwriter Drew Goddard, who was also responsible for
    adapting The Martian (which humorously won "Best Motion Picture -
    Musical or Comedy" at the Golden Globes). So it would be expected
    that the screenplay for the film would not be as serious in tone as
    the novel is.

    Still, book fans who have watched the movie, which had early
    screenings on March 16 as part of an Amazon Prime promotion, have
    expressed their disappointment on the movie's simplification of the
    science in a thread on the Project Hail Mary Reddit. Several
    comments say that Grace could have described the unique properties
    of the Astrophage more and that the movie could have explained that
    the drug Grace is injected with intentionally causes memory loss
    and gradual recall (which is why he starts the film not knowing
    what has happened and why he's on a spaceship to Tau Ceti in the
    first place). The book's exposition on the hibernation pods and DNA
    testing were cut down too, particularly the section that shows the
    laborious trial and error Grace goes through to breed taumoeba, an
    organism that eats Astrophage.

    The film instead chooses to streamline the novel's explanations to
    keep the runtime manageable and prevent the audience from being
    snowed by math and science. As noted by RadioTimes, the movie uses
    montages and bite-sized messages that Grace sends back to Earth to
    convey the science expediently. The movie then reduces the amount of
    time it takes for the scientist to connect his ship to the spacecraft
    of Rocky, the sentient stony-looking spider creature who quickly
    becomes the heart of the story.


    The Project Hail Mary film alters the source material in many ways
    That's hardly the only place where the movie separates itself from
    the source material. Lord and Miller, in an interview with Gizmodo,
    revealed that they added a "Don't Go Crazy" room to Grace's ship.
    This section of the craft, as seen in trailers, projects full
    360-degree screens of different environments as way of maintaining
    the mental well-being of the passengers. While this zen-like room
    isn't in the book, it's inspired by passages describing how the team
    on Earth were concerned about astronauts having cabin fever and going
    nuts having to look at the same walls every day and night.

    In addition, the film introduces different states of gravity for each
    room on the ship to give it more personality and visual surprise.
    This allowed the directors to convey how disorienting it is for Grace
    to wake up on the ship, as a way of interpreting his thoughts, of
    which there are many in the book, without having to explain the
    situation with internal dialogue. Lord explained that they "spent a
    lot of time trying to find ways that were in line and harmony with
    the soul of the book," ways that would be "additive to the book" so
    that the film could be seen as a "great companion piece."


    Many of the changes in the film were made to emphasize the emotional
    companionship between Grace and Rocky by removing or changing several
    plotlines. It cuts out a subplot about Eva Stratt, the leader of the
    Project Hail Mary initiative, choosing to hit the polar ice caps with
    nuclear weapons to release methane, artificially causing climate
    change. As dramatic as this is, it has little to do with the main
    characters.

    Another alteration in the middle of the film has Grace watching over
    Rocky's unconscious body after it saves him, making the creature's
    survival less assured than it is in the book. Then for the ending, the
    film omits the part where Rocky tells Grace that the probes he sent to
    Earth with samples of the taumoeba led to the sun being restored;
    instead, it shows a scene where Stratt receives the probes without
    Grace knowing if his efforts paid off. This makes Grace's decision to
    leave Rocky's planet, which both the book and the film make ambiguous,
    a stronger tug on the heartstrings.

    Taking this all into consideration, most of the comments in the
    aforementioned Reddit thread understand why the film chose to make a
    beeline through the science and focus on the relationship between Grace
    and Rocky. A handful who had read "The Martian" and then saw the movie
    had a similar reaction to Project Hail Mary, saying that it would take
    some time for them to accept the changes the movie made. This is
    despite Weir having cleared the changes himself. A few hope that an
    extended version of the film will be made that includes scenes that
    were left on the editing room floor. But even with the numerous edits,
    many still describe the adaptation as being "faithful" to the original
    story and appreciate the theatrical version as much as the source
    material.
