9. Insidious: Chapter 4
The Insidious franchise feels like it's already gone on for far too long, but 2018 will see the release of a third sequel in the seven-year-old series, and this time around, one of its best supporting characters will serve as the main protagonist.
In Insidious 4, parapsychologist Elise Rainier (Lin Shaye) will assume the mantle of lead character - despite dying in the first movie. Skills.
The film - which was originally set for release this year, before being pushed back - will follow Rainier as she investigates the haunting of her own family home.
The Insidious series has been a story of diminishing returns, and horror sequels, in general, are less satisfying than their predecessors, so it's hard to get too excited about a fourth entry, but perhaps the addition of Adam Robitel in the director's chair - a newcomer to the series - can inject some freshness into proceedings.
