'Catfish' & 'Paranormal Activity 3' Directors Henry Joost & Ariel Schulman Go 'Viral' In New Horror Trailer

With filmmakers Henry Joost and Ariel Schulman, the pair behind “Catfish” and uh, “Paranormal Activity 3,” you pretty can much assume you’re going to get something lean and twisty. And it looks like they deliver just that with their upcoming horror flick “Viral.”

Starring Analeigh Tipton and Sofia Black-D’Elia, the story centers on two sisters who must fight to survive when a deadly virus starts rolling through their town. There will be jump scares aplenty, which perhaps isn’t a surprise given that horror machine Jason Blum counts himself among the producers. Here’s the synopsis:

Teenaged sisters Emma (Sofia Black-D’Elia) and Stacey (Analeigh Tipton) live a normal life, until their small suburban neighborhood is stricken with a mysterious parasitic virus. As the disease rapidly spreads throughout the town, the two band together to barricade themselves from infection. But it may already be too late – when the virus enters their home, the sisters are faced with an impossible choice: protect each other, or survive the virus.

“Viral” opens in limited release and Digital HD on July 29th and lands on home video a few days later on August 2nd.
