Imagine swinging by a café to get a morning cup of coffee and encountering an angry, violent telekinetic woman. How would you react? What would you do? These are questions that unsuspecting members of the public had to answer in a prank set up by viral video marketing firm Thinkmodo.

In the prank, a man spills coffee on a woman’s computer and all hell breaks loose. She stands up and, ignoring his offers to help, throws him up against the wall. The tables around her slide away from her seemingly on their own, and books begin flying from the shelves. Once the “telekinetic” actress turns around and starts screaming, it’s safe to assume that the unassuming member of the public is scared out of their minds.

In reality, the elaborate setup was designed by Thinkmodo to advertise the upcoming movie Carrie, based on the novel of the same name by Stephen King. The café’s interior is an elaborate setup with pulleys and other elements of Hollywood magic designed to create astonishing live-action effects. The rest of the “customers” at the café are also actors in on the gag, and the customer at the counter seems to be the only one not in on the stunt.

The move is based on King’s first published novel, which helped establish his fame as a horror author. Through a collection of letters, newspaper clippings and other documents, it tells the story of Carrie, a much-maligned high school girl who develops telekinetic powers and uses them to exact revenge on her abusers in a small suburban U.S. town.

The movie is set to hit theaters in the U.S. on Oct. 18th, and a tie-in version of King’s novel is available on Amazon.
