14. World War Z
World War Z trades slow-burn zombie horror for large-scale chaos, following Brad Pitt as he races to stop a global outbreak. It’s more action-thriller than gorefest, but the towering zombie swarms and tense set pieces still pack a punch. | © Paramount Pictures

eXistenZ dives into body horror and virtual reality, blurring the line between game and reality until you’re not sure what’s real anymore. It’s weird, twitchy, and packed with Cronenberg’s signature flesh-tech visuals, perfect for fans of unsettling sci-fi. | © Dimension Films

12. Bad Taste
Bad Taste is Peter Jackson’s gloriously gory debut, a chaotic alien invasion flick packed with absurd humor, exploding heads, and zero restraint. It’s messy, loud, and proudly low-budget, but that’s exactly what makes it such a cult classic. | © Image Entertainment

11. Under The Skin
Under the Skin casts Scarlett Johansson as a mysterious alien who preys on unsuspecting men, only to slowly unravel in a world she doesn’t understand. Haunting, quiet, and deeply unsettling, it blurs the line between predator and victim in a way few sci-fi horrors dare. | © A24

4. Deep Blue Sea
Deep Blue Sea delivers exactly what it promises - genetically enhanced super-sharks turning an underwater lab into a blood-soaked maze. It’s over-the-top, chaotic, and knowingly ridiculous, but that’s exactly what makes it so entertaining. | © Warner Bros. Pictures

3. Invasion of the Body Snatchers
