Horror producer Jason Blum has revealed which of his own films scares him the most.

Since 2007, Blum has become one of the leading producers in the genre, backing bankable franchises including Paranormal Activity, Insidious and The Purge.

You’d be forgiven for thinking Blum doesn’t scare easily, but it turns out there’s one film he’s produced that left him feeling uncomfortable.

“When you’re producing you’re too inside the movie to get scared,” Blum told The Telegraph, adding: “but when I watched Sinister… it’s unnerving.”

Sinister, directed by Scott Derrickson, was released in 2012. It stars Ethan Hawke as a true-crime writer, who discovers a box of unsettling home movies in his attic.

The film made $87.7m (£67.3m) from a $3m (£2.3m) budget and spawned one sequel, which followed in 2015.

It’s a busy time for Blum with the release of three films – The Invisible Man, Fantasy Island and The Hunt, which had its release pulled following two mass shootings in the US in 2019.

The marketing for the film’s release is now leaning into the ban in a big way. It’s new tagline reads: “The most talked about movie nobody has ever seen.”

Written by Damon Lindelof and Nick Cuse, it follows 12 red-state strangers who wake up in a clearing and realise they are being hunted by liberals.
