Swedish theme park Gröna Lund is unafraid of using scary prank marketing year-round, but it couldn't pass up a chance to pull an extra terrifying stunt on April Fool's Day.
At a movie theater, Gröna Lund set up a kiss cam, which had several couples in the audience share a nice smooch—until one couple's lip-lock was interrupted by a zombie. After this, the cinema was plunged into darkness and all chaos seemed to break loose. Not knowing what was going on, the screams of the captive audience only seemed to cause more panic. After the audience had been properly stricken with fear, an ad was displayed on-screen for the theme park's House of Nightmares.
If this audience was in the theater for the purposes of watching a scary movie, this was a prime way to target an audience that's willing to experience a thrill.
