Netflix got fans of its hit show Stranger Things excited last week in London with a scavenger hunt turned experiential campaign to promote the upcoming season.
Locals in Shoreditch might have noticed posters advertising products that are featured on the show.
Billboards featured campaigns from the fictional brands Hawkins watches, Surfer Boy Pizza and Hawkins Power and Light - which had a phone number for passersby to call. Users of the forum noted that after calling the number they were met with an odd voicemail message.
Over the coming days, men in hazmat suits appeared at the out-of-home (OOH) activation and shadily began covering it up while urging people to step back. In a statement on Twitter, the official Netflix UK & Ireland account added that there was "nothing to see here".
