Pulse is a 2006 American techno-horror film directed by Jim Sonzero from a screenplay co-written by Wes Craven, and starring Kristen Bell, Ian Somerhalder and Christina Milian.

When Josh Ockmann enters a dark university library hoping to find a man named Douglas Ziegler, he is attacked by a humanoid spirit that sucks the life force out of him.

Dex and Mattie find the server and upload Josh's fix, causing the system to crash and the spirits to vanish.

Moments later, however, the system reboots, and the spirits return, leaving Mattie and Dex with no option but to flee the city by car.

Over the car radio, Mattie and Dex hear a report from the Army announcing the location of several "safe zones" with no Internet connections, cell phones, or televisions.

Kiyoshi Kurosawa, director of the original film, was initially expected to helm the remake before Craven became officially involved.

[3] By June 2002, Craven had written the script with Vince Gilligan, with Kirsten Dunst was eyed for the lead role.

[11][12] Final additions to the cast included Jonathan Tucker, Corryn Cummins, Rick Gonzalez, Riki Lindhome, Samm Levine, Amanda Tepe and Joseph Gatt.

[19] Jamie Russell of the BBC gave the film 2/5 stars, writing that director Sonzero "reboots the original's apocalyptic dread to produce a remake that ain't an upgrade.

"[20] Frank Scheck of The Hollywood Reporter said the film "isn't nearly as scary as watching your hard drive crash or having your BlackBerry conk out in the middle of a vital call.

"[21] Variety's Robert Koehler wrote: "Unlike Kurosawa's storytelling choices, which stressed a distended grasp of time and an atmospheric sense of dread that couldn't quite be pinned down, the new Pulse takes everything literally and is most concerned with turning Mattie into a blonde hottie in distress.

"[22] Nick Schager of Slant was more positive in his review, calling it "a reasonably sinister scary movie that faithfully taps into its predecessor’s irrational, existential dread and distrust of technology."

[23] In 2011, The Hollywood Reporter included Pulse in a list titled: "Halloween Gone Wrong: The 10 Least Scary Movies of All Time".
