Anyone who thought they were watching a sweet animation had a rude awakening when watching this creepy movie about a young girl called Coraline who discovers an idealised version of her own life through a hidden door - where nothing is truly as it seems.

With as many laughs as there are jump scares, Scary Movie 2 is a fun spoof of plenty of horror movies - and the perfect one for those who genuinely hate the real scary movie.

A Victorian romp full of spooky fog and even spookier headless horsemen, Johnny Depp is the cynic inspector tasked with discover who is gruesomely murdering villagers - and who the headless figure truly is. Starring Christina Ricci.

Here's Johnny! This iconic Stephen King adaptation follows a family who become custodians in an isolated hotel over the winter season - only to realise that there is so much more than just the three of them in the hotel - and that the biggest horrors can come from within. For a bonus, check out the sequel starring Ewan McGregor and Rebecca Ferguson, Doctor Sleep.

Horror king Jordan Peele's brilliant movie starring Lupita Nyong'o follows a happy, contented family who - while on vacation - are attacked by their exact doppelgangers who are known as the 'Tethered', who have lived underground all of their lives - and are ready to take revenge.

In this freaky horror film, Chris meets his girlfriend Rose's parents for the first time - only to become unnerved by her family, their friends - and their apparent fascination with him. The twist is a brilliant shock, and all we can say is to never meet your girlfriend's parents, just in case.

A young boy becomes increasingly concerned by the disappearances of his schoolmates at the hands of 'the Grabber' - before he becomes the next victim.

Adapted from a short story from Stephen King's son, fellow horror author Joe Hill, this is well worth the watch.

Aliens who hunt by hearing invade the Earth leading to an annihilation of the human race - leaving few survivors who manage to keep alive by not making a single sound. The story follows a family who, struggling with grief, fight for survival - despite forces growing against them.

If you love a spooky Victorian horror, this is the one for you. Daniel Radcliffe stars as a widowed lawyer who travels to a remote country home to settle a widow's affairs - only to become entangled in a local ghost story about the 'woman in black'. The story? If you witness her ghost, then a child dies. We'll give you a spoiler, it's not just a story…

A classic slasher film that follows a group of teenagers who, one by one, become the victims of Freddy Krueger, a child killer who can murder through dreams - so whatever you do, stay awake.

Nicole Kidman is terrifying in this jumpscare horror about a woman who lives with her two children - both allergic to sunlight - in total isolation while her husband is away fighting in the Great War. When the house staff suddenly deserts her, she quickly hires three servants who come looking for work - but there is so much more to them then what meets the eye.

With a famously excellent plot twist, the story follows a child psychiatrist who wants to help Cole, a troubled young boy who has a dark secret that he hides from his mum, a single parent desperate to help him. If you haven't watched, this eerie movie is a must watch.

The latest body horror to hit our screens - this Demi Moore and Margaret Qualley movie is seriously grotesque.

And as you can imagine, the rules are broken. 

As well as giving us an iconic monologue from Toni Collette, Hereditary quickly become a creepy classic following it's release in 2018.

Or, indeed, hang your head out of a moving car.

A movie so scary that some of us still don't sleep in rooms with televisions, the story follows a woman who watches a horrific movie only to receive a phone call that she has seven days to live. Desperate to save herself, she attempts to trace the source of the call and break the curse - before it's too late.
