While blockbusters grab the spotlight, a trove of lesser-known gems has left an indelible mark on my heart. If you want to venture beyond mainstream titles, here are some of the best SF movies you’ve probably never seen.

“The Island,” directed by Michael Bay, tells the gripping story of Lincoln Six Echo (Ewan McGregor) and Jordan Two Delta (Scarlett Johansson), who find themselves in a seemingly perfect but confined world. As the narrative unfolds, we discover that they and the rest of the community are clones designed to provide “spare parts” to their original human counterparts. Lincoln’s growing suspicion leads to the revelation of this reality, propelling them to escape into the real world.

What makes “The Island” outstanding is its unique blend of action-packed sequences, a compelling storyline, and thoughtful ethical questions it raises about human cloning and morality. Beyond the impressive stunts and visuals, the film contemplates the essence of humanity, freedom, and the lengths one would go to preserve it.

2. ‘In Time’ (2011)

Set in a dystopian future, “In Time” introduces us to a society where time has become the ultimate currency.

Justin Timberlake plays Will Salas, a man from the poor time zones who finds himself accused of murder after receiving a windfall of time from a centenarian.

The brilliance of “In Time” lies in its allegory. The film subtly critiques social inequality, drawing parallels to the disparities in our current societies. It presents a world where the rich live forever, and the poor are literally racing against time. The concept is innovative, and its execution forces viewers to question the value of time and the costs of immortality.
