Sure, this is an obvious promotion for a horror movie when you're watching it safely at home. But would it scare the hell out of me if I just randomly saw it in the street? Yes, of course.
The robotic hell child was designed by "viral marketing company" Thinkmodo—who made last fall's Carrie prank—to promote the awful looking horror movie, Devil's Due. Using a three man team—one for the stroller and two for the demon baby—the company terrorized unsuspecting people throughout Manhattan earlier this winter.
My advice? In addition to steering clear of that movie, stay away from all strollers, just in case this thing is hiding inside.
