A new wave of low-budget ‘smart’ horror movies is challenging the studio behemoths with a recipe that swaps gratuitous gore and elaborate special effects for good old-fashioned suspense.

‘Don't Breathe,’ which is due for release next week on the back of widespread acclaim, is hoping to emulate the success of ‘The Babadook,’ ‘It Follows’ and a series of other creepy hits made on a shoestring.

While they lack the marketing muscle of the summer tentpoles, these films often become word-of-mouth hits, gathering momentum as reviewers praise their uncompromising refusal to rely on the usual horror tropes.

‘Mainstream horror these days is really all about whatever's clever -- a new twist on an old story, or one hell of a trailer,’ Jeff Bock, of film industry research firm Exhibitor Relations, told AFP.

‘As we've seen lately, 'smart' horror films are in vogue right now,’ he said, adding however that there would always be excitement when ‘a horror icon is revived for one more hunt.’

‘It Follows’ (2014), a thematically rich modern slasher that takes its cue from the 1980s output of masters like Wes Craven and John Carpenter, is often cited as the jewel in the crown of horror's new wave.

Its director David Robert Mitchell was acclaimed for weaving the cliche of teenagers menaced by a malevolent supernatural force into that rarest of things -- a scary movie that drips with subtext and not just blood.

- Jump scares -

One of its leads, Daniel Zovatto, also stars in Fede Alvarez's ‘Don't Breathe,’ which hits cinemas on Friday and is the director's second feature after the 2013 remake of horror classic ‘Evil Dead.’

Made on a budget of just $10 million, ‘Don't Breathe’ follows a trio of friends who break into the house of a blind recluse, confident of an easy pay day, only to find themselves in a terrifying life-or-death struggle.

‘At the time when we first showed the movie people had no idea what it was about. There was no trailer, there was nothing,’ says Zovatto, a 25-year-old Costa Rican actor last seen in AMC's zombie show ‘Fear the Walking Dead.’

‘Don't Breathe’ is unusual in that there are very few jump scares -- a staple of the teen slasher end of the horror genre -- and those that do feature feel like they've been earned.

Zovatto, who appears with stage and screen veteran Stephen Lang, relative unknown Dylan Minnette and ‘Evil Dead’ star Jane Levy, says he grew up watching horror movies, but was often disappointed.

‘I think there were a few years, especially in my teenage years, where I would go and watch films in this genre and I was just devastated because I didn't really get to see something that I liked,’ he says.

‘And I feel like this whole new wave brought a new perspective to the genre and new directors like Fede Alvarez and David Robert Mitchell -- and they are changing the game.’

- Spoonfeeding -

Alvarez, who brought in almost $100 million with ‘Evil Dead’ on a $17 million budget, prides himself on trying to ‘spot what everyone else is doing and (running) in the opposite direction.’

After directing a relatively conventional remake, the 38-year-old Uruguayan wanted to avoid haunted houses, chain saws, zombies and all the other go-to devices in the horror toolkit.

Brought up by his father on a diet of Alfred Hitchcock -- ‘Psycho,’ followed by ‘Vertigo,’ ‘Strangers on a Train’ and many of the others -- Alvarez says that, for him, horror was ‘never the scares and the jumps, it was always about suspense.’

‘A couple of things I love and I wanted to bring to this film: one was suspense and the second one is that the characters always have shady morals,’ he told AFP.

‘If you take Janet Leigh stealing money in 'Psycho,' or in 'Strangers on a Train' obviously plotting to kill the guy's wife... they're not your everyday Hollywood heroes.’

If you give your central characters nuance, he argues, you'll keep the filmgoers guessing about who they should be rooting for, who deserves to survive, who should get the money and how it's going to end.

‘I like that you have to choose who to root for and I'm not spoonfeeding you about who's a hero and who's a villain, who's the funny guy,’ the director said.
