Today’s film arrived on Earth just as it was about to be destroyed during the disaster movie heyday of the late ’90s. That meant it had to compete with major classics of the subgenre that were still fresh in the minds of audiences everywhere. As if that weren’t daunting enough for a film hoping to become the thinking man’s end-of-the-world epic, it also had to contend with the loss of a major Hollywood director and the visual effects complexities of breaking off a massive chunk of Earth. Worst of all, a major Hollywood studio would allegedly not only steal their idea, but fast-track their own version for release that same summer…with double the budget. It’s the movie that tried to differentiate itself from the spicy spectacle of its brethren by leaning into real-life science and emotion. But would it succeed? This is the story of what happened to Deep Impact.
The story begins as far back as the late 1970s when producers David Brown and Richard Zanuck were looking to update the 1951 disaster film When Worlds Collide, about a rogue star threatening to destroy Earth. They took the project to legendary Jaws director Steven Spielberg, who was interested but busy creating his own disaster piece: an adaptation of Arthur C. Clarke’s novel The Hammer of God. The story centered on an asteroid discovered to be on a collision course with Earth, forcing humanity to attempt deflecting it with fusion thermal rockets. Eventually, the filmmakers decided to merge the two stories into one grand idea.
Jacob’s Ladder writer Bruce Joel Rubin went to work on a script later revised by The Player writer Michael Tolkin. By the end of development, the story had taken on enough of its own identity that neither original inspiration received credit. This reportedly infuriated Arthur C. Clarke, who later gave the film a scathing review.
While The Hammer of God sounded undeniably badass, it was ultimately abandoned in favor of the disaster film title Deep Impact, which admittedly sounded a little less like science fiction and a little more like late-night cable programming. The production knew it too. In fact, the team reportedly held a competition at ILM to come up with a better title, but nobody ever did.
Meanwhile, The Walt Disney Company had no trouble naming their own asteroid disaster blockbuster: Armageddon. Sound familiar?
Deep Impact writer Bruce Joel Rubin later claimed he was discussing Deep Impact with Disney executives during a meeting about an entirely different project when he noticed one executive suspiciously taking notes. Shortly afterward, Armageddon was announced. Coincidence?
Like it or not, the two films would be forever linked. There was no “Barbenheimer” dynamic between the two movies during the summer of 1998. These were direct competitors battling for dominance during the golden age of cinematic destruction.
Just two years earlier, audiences had already experienced films like Twister, Independence Day, and Dante’s Peak. Disaster movies were everywhere. Tommy Lee Jones was battling volcanoes in downtown Los Angeles. We were absolutely obsessed with watching the world end, and it ruled.
Spielberg originally planned to direct Deep Impact himself, but because the studio was forced to compete with Disney’s accelerated timeline, he ultimately had to step aside while finishing work on Amistad. The directing duties instead went to Mimi Leder, fresh off her work on ER. According to Leder, she was unexpectedly offered the job while sitting in the editing room for her previous feature, The Peacemaker.
Leder’s contribution to the film was enormous. She approached the project as a human drama that happened to feature massive visual effects, rather than the other way around. That philosophy perfectly explains the difference between Deep Impact and the wildly entertaining Armageddon.
Some viewers would say one movie is boring while the other is fun. Others would argue one is ridiculous while the other is thoughtful and grounded. In reality, audiences won because they received two completely different disaster films tackling similar subject matter.
Leder also brought in The Peacemaker cinematographer Dietrich Lohmann. Tragically, Lohmann became ill with leukemia during production and was unable to complete the film. Contact cinematographer Don Burgess stepped in when needed as Lohmann’s health declined. Lohmann sadly passed away in November 1997.
A thinking man’s disaster movie required an earnest cast, and a massive one at that. Morgan Freeman played the President of the United States, tasked with repeatedly informing the public that humanity was essentially doomed. At one point, Freeman reportedly requested that the President wear a single earring. The request was denied, though audiences can still spot an impressive arm tattoo during one home scene.
Robert Duvall delivered a heartfelt performance as the leader of the mission sent to divert the comet from Earth’s path. Téa Leoni starred as the journalist who uncovers the incoming extinction event while investigating what she initially believes is a White House infidelity scandal. Despite receiving a nomination for Worst Supporting Actress at the Stinkers Bad Movie Awards, Leoni is genuinely excellent in the role.
The supporting cast was stacked with talent, including Blair Underwood, Jon Favreau, James Cromwell, Vanessa Redgrave, Leelee Sobieski, and Elijah Wood.
The story explored every layer of a fictional extinction-level event, jumping from government officials to astronauts to ordinary civilians awaiting the possible end of the world. Leder originally wanted the film to feature even more international perspectives, but the budget and schedule simply wouldn’t allow it. Several scenes featuring supporting characters were ultimately cut to reduce the runtime.
Deep Impact may be more emotional than many of its peers, exploring themes of family, sacrifice, and acceptance…but eventually, disaster movies still have to blow stuff up. That’s where Industrial Light & Magic came in.
To create the film’s destruction sequences, ILM combined physical miniatures, real water and smoke effects, early CGI, and clever editing techniques to make the devastation feel as realistic as possible.
For the nightmare-inducing tidal wave sequence, the effects team used early fluid simulation software capable of generating millions of digital water particles. They combined those simulations with footage of real splashing water, miniature buildings, digital humans, debris, and fire to create the massive wall of destruction.
For the space scenes, the filmmakers relied heavily on physical spaceship models filmed against blue screens, with planets and stars added later in post-production.
The practical effects work is a major reason the visuals still hold up today. Instead of relying entirely on computers, the production blended digital effects with old-school model work and practical filmmaking techniques, all while racing against an aggressive production schedule during the early days of CGI water simulation.
For the comet surface scenes, the production used extensive blue-screen work alongside practical rocky terrain sets. Actors wore wire harnesses to simulate altered gravity and help them navigate the unstable terrain.
While several crowd shots throughout the film utilized CGI, the massive Virginia traffic jam sequence was entirely practical, involving roughly 1,800 vehicles supplied largely by volunteers from the Manassas, Virginia area.
Spielberg remained heavily involved as executive producer throughout filming. Near the end of production, he reportedly requested additional scenes and shots to clarify potentially confusing story points for audiences. And when Spielberg talks, you listen.
Another major factor separating Deep Impact from many disaster films of its era was its commitment to scientific realism. The production assembled a large team of scientific advisors that included astronomers, astronauts, and NASA personnel to help ground the story in believable science. While Armageddon famously received criticism for its scientific inaccuracies, asteroid expert Clark Chapman reportedly described Deep Impact as a “fairly good” representation of how such a scenario might unfold.
Visual effects supervisor Scott Farrar later said he heard from scientists and viewers around the world impressed by the film’s realistic approach.
Leder managed the enormous scope of the production by dividing it into distinct categories: dialogue-driven drama scenes, government and press conference sequences, and the massive visual effects set pieces.
Screenwriter Bruce Joel Rubin was even granted access to highly classified federal locations, including the White House Situation Room, while researching the screenplay, an opportunity he credited in part to Spielberg’s influence.
Despite all of this, Deep Impact still lived somewhat in the shadow of Armageddon and Michael Bay’s hyperactive “hold my beer and fireworks” filmmaking style. After all, how do you compete with Aerosmith, exploding asteroids, and Ben Affleck doing Animal Cracker puppet routines on Liv Tyler’s stomach? Deep Impact’s greatest advantage was presenting itself as the emotional alternative to all the chaos, complete with a moving score by James Horner that emphasized humanity, sacrifice, and hope in the face of extinction.
Deep Impact reached theaters first with a May 8, 1998 release date. Armageddon followed less than a month later on July 1, 1998. Made for roughly $75–80 million, Deep Impact earned over $41 million during its opening weekend and ultimately grossed just under $350 million worldwide.
That success impressed many observers, though Leder later expressed disappointment with the media’s obsession over pitting the two films against one another. She argued that both movies offered completely different experiences, and she was right.
Armageddon, produced with a budget closer to $140 million, also became a massive hit, eventually earning more than $550 million worldwide.
Critical reception for Deep Impact was mixed, which honestly makes sense. Viewers looking for emotional drama and scientific realism appreciated the film’s grounded approach, while others felt it became too bogged down in emotion and exposition to deliver the full-throttle insanity audiences expected from disaster blockbusters.
The movie also forced audiences to confront some deeply uncomfortable ideas about humanity’s possible extinction. There’s something strangely haunting about hearing an uplifting Amblin-style score while an estranged father and daughter embrace on a beach as the sky turns red and an apocalyptic tidal wave barrels toward them. It’s hopeful and horrifying at the same time.
But hey, Earth survived. And we all got to learn what happened to Deep Impact.
