Gerard Butler and Morena Baccarin reprise their roles in this 2026 post-apocalyptic sequel, which sees the Garrity family leaving their bunker to journey across a devastated Earth in search of a new home after a comet strike. What is the title of this film?

The film matching the description, featuring Gerard Butler and Morena Baccarin reprising their roles as the Garrity family venturing out from their bunker in 2026 across a post-apocalyptic Earth, is titled Greenland 2: Migration (Review). This movie serves as the direct sequel to the 2020 disaster film "Greenland," continuing the harrowing story of a family's fight for survival after a devastating comet strike. The provided details, from the returning cast to the plot of seeking a new home in a ravaged world, align precisely with the premise of this follow-up film.

The original "Greenland" introduced audiences to John and Allison Garrity, along with their young son Nathan, as they desperately sought refuge in a secret underground bunker in Greenland amidst the impending impact of a planet-killing comet named Clarke. The first film focused on their perilous journey to reach safety. "Greenland 2: Migration" picks up five years after the initial catastrophe, when the family is compelled to leave the relative safety of their bunker. Their new mission involves a dangerous trek across a decimated Europe, enduring the harsh realities of a world fundamentally altered by the comet, in their search for a truly habitable new home.

Ric Roman Waugh, who directed the critically noted first installment, returned to direct "Greenland 2: Migration," maintaining the consistent tone and vision of the series. Gerard Butler and Morena Baccarin once again lead the cast as the resilient parents, though the role of their son, Nathan, was taken over by Roman Griffin Davis for the sequel. The film delves deeper into themes of human endurance and the emotional toll of living in a post-apocalyptic landscape, offering a compelling, albeit grim, narrative of survival and hope.
