What if you received a government alert stating that the world was ending in 48 hours, and you weren’t on the list to be saved? That’s the nightmare the Greenland movie throws you into.
Forget zombies or out-of-this-world survival plots. Greenland is a modern world ending event: an extinction-level event, government triage, societal collapse, and families scrambling to survive while the clock runs out. It’s a brutal look at what may happen when the worst happens and people fight to survive.

TL;DR: Greenland is a realistic, high-stakes survival film that shows what happens when time runs out and the system decides who lives. It’s a wake-up call for preppers—and anyone who wants a glimpse into the effects of a massive comet strike on the earth.

Why I Like This Movie
This one sticks with you—because it’s plausible. A massive comet is on a collision course with the planet. Society as we know it will end. It shows what collapse might actually look like. Sirens blare, TV anchors panic, and families must decide whether to help others or say “No.” Panic breaks out—riots start—and the world slides off a cliff on the way to impact.
I like that it shows both sides: those inside the system (as part of an official government evacuation) and those who are left to face the grim reality of a society ending comet impact. It also highlights the dynamics between those who have a plan and those who don’t, and the chaos that can ensue when the rule of law breaks down.

Preparedness & Survival Lessons
1. If you’re not one of the privileged, you’re on your own: When the alerts go out, most people are not on the list of those whom the government is saving. As that realization sets in, those on the list or confronted with a tsunami of pleas for help are affected. What do they do? Greenland brings home a harsh truth about disasters. You can’t save everyone, so what do you do?
2. Medical needs become critical fast: Treat your life-sustaining medications as precious cargo. Only let those people who you know to be capable and responsible carry anything that lives depend on. Split up your life-sustaining supplies across multiple locations, so losing one isn’t a major problem.
3. Quick Response is life: When the world goes sideways, those who hesitate may find themselves behind the power curve and suffering as a result. You need to be packed, ready, and decisive. Your mindset should be one of—grab your bags and go!
4. Relationships are force multipliers: Knowing where to go and whom you can trust can mean the difference between life and death. Building networks of mutually supporting loved ones and friends can be a huge help when you need it most.
5. You are your own first responder: The government has a poor record of saving people from disasters. Don’t count on it to save you. You have to be ready to be your last best option.
