15. The Blob (1958)
The movie: A low-budget B movie about small town chaos, The Blob was so popular with audiences that it was moved up to feature film status. The special effects might be daffy, but it gave Steve McQueen his first ever leading role.
The monster: A gelatinous pink, er, blob that arrives in a meteor and sets about eating everything in its path.
14. Predator (1987)
The movie: Iconic sci-fi actioner with Arnie leading a team of elite forces into the jungle to rescue hostages, only to find himself hopelessly outmatched by a lethal creature - the Predator.
The monster: Tall, dreadlocked, with terrifying bug-like mandibles, the Predator is a member of the alien Yautja race. They like to hunt and view Earth as a massive game reserve.
13. Jurassic Park (1993)
The movie: Spielberg's incredibly ambitious science-fiction adventure changed cinema, not least with its innovative use of CGI to bring the park to life. Monster movies would never be the same again.
The monster: The park boasts many different kinds of resurrected dinosaurs, but the most monstrous are the Tyrannosaurus rex and the velociraptors, both of whom will eat visitors given half a chance.
12. The Descent (2005)
The movie: A chiller by Dog Soldiers director Neil Marshall that's gone on to achieve well-deserved cult status among horror hounds. Deciding to follow the "YOLO" way of thinking, six women enter an unmapped cave system for a weekend of dark and gloomy frolics and soon find that they're a bit trapped. Shortly thereafter they're hunted by very hungry subterranean meanies.
The monster: Flesh-eating humanoids known as Crawlers. They live underground. Marshall envisioned the monsters as cavemen who never left the caves and ended up evolving in the dark. Could this really happen?
11. The Fly (1987)
The movie: In true Cronenberg style, this remake of a '50s sci-fi is pure body horror. Every stage of Brundle's transformation into the fly is gross you'll never be able to look at a donut the same way ever again.
The monster: Brundlefly is a properly repulsive man-fly hybrid, created when Seth Brundle (Jeff Goldblum) tries to transport himself across the room but accidentally invites a fly to the matter-reconstructing party.
10. Creature From the Black Lagoon (1954)
The movie: Another Universal horror, this one sees a group of explorers setting out to find a mysterious lagoon to investigate some mysterious fossils that have washed up on the banks of the Amazon. Shot in 3D, it was released too late for the '50s 3D boom, but even without the gimmick it's a classic monster movie.
The monster: The Gill-man is a sort of amphibious fish-man hybrid, all scales and webbed feet and super strength.
9. Jaws (1975)
The movie: Widely dubbed as the first blockbuster ever made. The town of Amity Island is expecting a normal summer season but is instead met by gnarled, chewed bodies when a toothy fish comes swimming into the bay. Spielberg's summer scarefest kickstarted a global fear of great whites that's still prevalent today.
The monster: Oh you know him. The great white shark whose fondness for sun-kissed flesh is nearly rivalled by his fondness of showing off his pearly whites.
8. Dracula (1931)
The movie: An adaptation of the stage adaptation of Bram Stoker's novel, there are some liberties taken with the source material, but the atmosphere is pure Gothic eeriness.
The monster: One of the most recognisable monsters of all time, Bela Lugosi's Count Dracula is part suave foreign gentleman, part ruthless bloodsucker.
7. Nosferatu (1922)
The movie: A silent classic that was almost lost forever because Bram Stoker's widow took legal action against the filmmakers, Nosferatu is a masterclass in light and shadow.
The monster: Another adaptation of Dracula, but an unauthorised one so the vampire here is Count Orlok (Max Schreck), and he's much more monstrous than the Lugosi version, all massive fangs and endless fingernails.
6. Godzilla (1954)
The movie: When ships start going missing off the coast of Odo Island, an investigation is launched but its not hard to solve the mystery when a giant lizard creature attacks Tokyo. The whole thing is a metaphor for nuclear war and it was so popular that 27 sequels were produced, plus countless copycats.
The monster: Godzilla is the most iconic of the Japanese nuclear monsters: a giant lizard that lives in the sea and only surfaces when driven to rage by atomic bomb testing.
