Best Sci-Fi Movies For A Movie Marathon From The 2020S That Flew Under The Radar

The Moviepiq team picked these sci-fi films specifically for a movie marathon. No filler. Every film on this list earns its place for exactly this occasion.

The best sci-fi movies for a movie marathon from the 2020s that flew under the radar. Includes Belle, The Gorge, Sonic the Hedgehog 3 and more - curated by M...

A movie marathon lives or dies on the quality of its list. Start strong, vary the pace, and make sure at least one film in the sequence is one nobody in the room has seen.

Despite everything, the 2020s have produced some genuinely remarkable cinema. Films made under pressure that somehow carry none of it.

Great sci-fi uses the impossible to illuminate the real. Distance from the present is what allows these films to say things that otherwise couldn't be said.

2021 · ★★★½☆ 7.6/10

It's up to the heroes to save the world and the future of heroes in what is the most dangerous crisis to take place yet in My Hero Academia.

These films use the grammar of science fiction — the technology, the strangeness, the distance — to say things that couldn't be said any other way.

2021 · ★★★½☆ 7.5/10

The world is stunned when a group of time travelers arrive from the year 2051 to deliver an urgent message: Thirty years in the future, mankind is losing a global war against a deadly alien species. The only hope for survival is for soldiers and civilians from the present to be transported to the future and join the fight. Among those recruited is high school teacher and family man Dan Forester. Determined to save the world for his young daughter, Dan teams up with a brilliant scientist and his estranged father in a desperate quest to rewrite the fate of the planet.

The films that fly under the radar often do so because they resist easy categorisation. That resistance is usually exactly what makes them worth finding.

Great science fiction stays with you because the questions it raises don't have answers. These films plant something and leave it to grow.
