Director's Stuntman Past: Director Ric Roman Waugh, a former stuntman, prioritized practical effects and consulted with NASA for procedural accuracy, giving the film a grounded, realistic feel.
Beard Transformation Surprise: Gerard Butler shaved his beard mid-film to symbolize his character's desperation, but the on-screen moment used Butler's real-life transformation, surprising co-star Morena Baccarin.
Comet Clark's Inspiration: The planet-killing comet "Clark" is named after sci-fi legend Arthur C. Clarke, whose 1993 novel The Hammer of God featured a similar Earth-threatening asteroid impact.
Atlanta Doubles as Disaster Zones: While the film depicts global destruction, many exterior shots, including the fiery air burst in Chicago, were filmed in Atlanta, Georgia, using practical pyrotechnics.
Insulin Pump Realism: The addition of young Nathan's insulin pump dependency was added to the script during production to heighten the family's vulnerability and add real tension to the scenes.
