The most talked-about science fiction film of the year has finally arrived, and if the opening weekend numbers and crowd reaction are any indication, Project Hail Mary is not just a hit, it may be the defining theatrical event of 2026.
The film, directed by Phil Lord and Christopher Miller and based on Andy Weir’s bestselling 2021 novel, opened in theaters nationwide on March 20, 2026, distributed by Amazon MGM Studios. Ryan Gosling stars as Ryland Grace, a middle school science teacher and former molecular biologist who awakens alone on an interstellar spacecraft with no memory of how he got there. As his memories slowly return, he realizes he is humanity’s last hope against a mysterious organism, called Astrophage, that is slowly dimming the sun and threatening all life on Earth. Screenwriter Drew Goddard, who previously adapted Weir’s The Martian for the big screen, returns to handle the adaptation, and the reunion appears to have been well worth the wait.
Critical reception has been nothing short of extraordinary. Out of 260 reviews counted by Rotten Tomatoes, a full 95 percent are positive, earning the film a prestigious Certified Fresh designation. The site’s consensus reads that the film is a near-miraculous fusion of smarts and heart, carried along effortlessly by the gravitational pull of Ryan Gosling at his most winning. Metacritic places the film at a 77 based on aggregated critic opinion, landing it squarely in “generally favorable” territory. One reviewer described the film as a Spielbergian blast of energy, wit, and heart, while others called it the first great blockbuster of 2026 and praised its ability to turn dense scientific concepts into crowd-pleasing, emotionally resonant cinema.
Audiences have been equally, if not more, enthusiastic. The Rotten Tomatoes verified audience score has settled at a remarkable 98 percent, a figure that has already broken records. According to tracking data, this represents Ryan Gosling’s highest ever audience score on the platform. It also stands as the highest audience score for any film directed by Lord and Miller, and ties for the highest-scored science fiction film in over a decade. Social media monitoring firm RelishMix reported that a social media universe of more than half a billion users was buzzing about the film, with the loudest applause coming from book loyalists who recognized in the adaptation a rare crowd-pleaser with brains, heart, and genuine theatrical pull.
Then came the number that the industry pays closest attention to. CinemaScore, which surveys opening-night moviegoers as they exit theaters across the country, awarded Project Hail Mary an official grade of A. It is a result that places the film among the most warmly received wide-release blockbusters of recent years, and it carries real financial significance. A CinemaScore of A or higher is consistently one of the strongest predictors of a film’s ability to hold at the box office in the weeks following its debut, driving strong word-of-mouth and repeat viewings. For a $200 million original science fiction film banking on legs rather than franchise loyalty, an A from first-night audiences is about as reassuring a signal as a studio could ask for.
That grade aligns perfectly with the PostTrak exit data that began coming in during Thursday preview screenings. On PostTrak, the industry exit-poll service from Screen Engine and Comscore, Project Hail Mary scored a perfect five stars, with an overall positive score of 95 percent and a massive 85 percent definite recommend, meaning more than eight in ten preview-night viewers were actively urging others to see the film. Numbers like these are the closest thing to a standing ovation that box office science can measure.
The box office has validated all of that enthusiasm in dramatic fashion. Preview screenings, which included special 70mm showings, IMAX engagements, and early Amazon Prime member screenings beginning March 16, raked in $12 million, the second-highest preview total ever recorded for a non-sequel film, trailing only the $13.5 million earned by It in 2017. By Friday evening, the film was tracking toward a $71 million domestic opening weekend, which would set the all-time record for Amazon MGM Studios and surpass Creed III’s previous record of $58.3 million. Globally, the film is projected to cross $100 million in its opening frame across 82 international markets. If those projections hold through Sunday, Project Hail Mary will tie Jordan Peele’s Us as the fourth-best opening weekend ever for a non-franchise film, sitting in the same rarified company as Oppenheimer, I Am Legend, and the original Avatar.
Much of the credit for the film’s warm reception is being directed at Gosling’s performance, which critics have called possibly the best work of his career. For a film that is essentially a two-and-a-half-hour story of one man alone in space, the pressure on a single actor to carry the emotional weight is immense. Reviewers noted that Gosling rises to meet it, blending comic instincts with genuine vulnerability in a way that keeps the film from ever feeling cold or mechanical. James Ortiz, who serves as the voice and lead puppeteer for the alien character Rocky, has also drawn considerable praise, with audiences responding to the friendship between Grace and Rocky as one of the most touching and original in recent blockbuster memory.
For Amazon MGM Studios, the opening represents more than a box office milestone. The studio has spent years trying to establish itself as a reliable home for theatrical event cinema, and Project Hail Mary is being read by many in the industry as its clearest statement of intent yet. When studio presentations were made at CinemaCon, theater owners in attendance reportedly singled out this film as the title giving them the most hope for the theatrical marketplace. Those hopes appear to be paying off in real time.
With relatively light competition on the horizon before The Super Mario Galaxy Movie opens in early April, Project Hail Mary has every opportunity to display the kind of week-to-week staying power that could push its domestic total toward the $200 million range. The Martian, the last Weir adaptation from a major studio, earned $228 million domestically and $630 million worldwide on the strength of exceptional legs. Whether Project Hail Mary can match or exceed that performance remains to be seen, but with a CinemaScore of A, a 98 percent audience score, a $71 million opening weekend in progress, and an entire solar system worth of goodwill from critics and moviegoers alike, it is off to an extraordinary start.
