The first glimpse of a film is a marketing tightrope. Tease too much, with fractured voiceovers and obscure, unrelated images and you risk a healthy dose of WTF (or, more likely, WSIC – why should I care). Show too much and you’ve given people a beat for beat highlight reel of the whole film.

Catfish directors Henry Joost and Ariel Schulman are returning to the momentum-fuelled world of technology for their latest film, Nerve, which has Emma Roberts and Dave Franco is various states of undress playing an online game of Truth or Dare.

The first trailer has arrived and gives the entire game away.

It’s an engaging trailer to be sure, and as was shown recently with the zeitgeist-propelled Skype thriller Unfriended there’s great hay to be made using everyday technology to chill a few spines.

The film is released on the 27th of July, check it the film trailer below,
