10 Horror Movie Background Scares That Will Scar You For Life

10. The Coat Boy - Insidious

Back in 2010, Insidious spawned a sizeable franchise that's still going today, and formed one of the pillars of modern blockbuster horror cinema, alongside The Conjuring and The Purge.

In the film, parents Josh and Renai Lambert (Patrick Wilson and Rose Byrne) summon a psychic and paranormal investigators to take back their new home from malevolent forces and rescue their supernaturally comatose son Dalton (Ty Simpkins).

While there are plenty of scares in the film's hundred minutes of runtime, including more cheap and cheerful jump-scares than you can wave a monkey's paw at, there are a couple that director James Wan (known also for Saw and The Conjuring) slipped in under the radar.

In one scene when Renai is unpacking by herself, she comes face to face with the old-timey spirit of a young boy, who dances and runs through the house to "Tiptoe Through The Tulips". What you might not have noticed on first viewing, however, is the ghost boy standing by the coat rack with his face to the kitchen wall, before Renai has ever laid eyes on him.

Makes you wonder what else you might have missed...
