Greenland is a 2020 American apocalyptic survival disaster thriller film directed by Ric Roman Waugh and written by Chris Sparling.

The film stars Gerard Butler (who also produced), Morena Baccarin, Roger Dale Floyd, Scott Glenn, David Denman, and Hope Davis, and follows a family who must fight for survival as a planet-destroying comet races to Earth.

Structural engineer John Garrity lives in Atlanta, Georgia with his estranged wife, Allison, and their diabetic son, Nathan.

While at the supermarket, John receives an automated Department of Homeland Security (DHS) message announcing that he and his family have been selected for emergency sheltering.

John then receives a call with instructions to head to Robins Air Force Base for an evacuation flight, as Clarke is on a direct collision course to Earth and will impact the entire planet to cause an extinction-level event in two days.

As John exits the base, a panicked mob breaks in, destroying several evacuation planes when gunfire ignites spilled jet fuel.

A passenger named Colin tells him they are headed to Osgoode, Ontario, where private planes are flying to Greenland, believed to be the military evacuation site.

While making steady progress to Osgoode, the family learns over the radio that Clarke's largest fragment, which is 9 miles (14 km) wide, will hit Western Europe and obliterate it.

The Garritys and other occupants exit the shelter, as reports came in that the atmosphere is finally clearing, giving the survivors the chance to bring Earth back onto its feet.

[18] On its first day of release in France, the film made $255,000 with 31,000 tickets sold, 61% ahead of Butler's Olympus Has Fallen (2013) despite fewer theaters and tight COVID-19 restrictions.

The website's critics consensus reads: "Beware, comets of Greenland: Gerard Butler is here to protect Earth – and show audiences an improbably entertaining time.

[29] Writing for the Chicago Sun-Times, Richard Roeper gave the film three out of four stars, saying, "Unlike the typical, effects-laden, comet-threatens-the-planet B-movie, Greenland is more in the vein of Steven Spielberg's War of the Worlds, with the scenes of chaos and destruction serving as the backdrop for the story of one family's desperate quest for survival — even when circumstances have ripped them apart.

"[30] Writing for IndieWire, David Ehrlich gave the film a grade of B and said, "By eschewing spectacle and focusing on the human scale of a crisis, Greenland becomes the rare disaster movie that feels realistic.

[32] Jordan Mintzer of The Hollywood Reporter said "The gritty verisimilitude that the star and director Ric Roman Waugh bring to the table goes a long way in making this B-level blockbuster a timely and guilty pleasure".

[34] According to Matthew Monagle of The Austin Chronicle, "Greenland might be a B-movie at heart, but in keeping at least one toe on the ground at all times, the filmmakers craft something that punches well above its weight class".

[37] In June 2021, it was announced a sequel titled Greenland: Migration was in development, and will reportedly center on the Garritys' journey across a frozen European wasteland to find a new home.
