Lego Stranger Things

Lego Stranger Things (stylized as LEGO Stranger Things) was a Lego theme based on the 2016 Netflix sci-fi horror series of the same name created by the Duffer Brothers. It was licensed from Netflix. The theme was first introduced in May 2019 and was discontinued in December 2022.

Overview
Lego Stranger Things was based on the Stranger Things 2016 Netflix sci-fi horror series, which focuses on the investigation into the disappearance of a young boy (Will Byers) amid supernatural events occurring around the town, including the appearance of a girl with psychokinetic abilities (Eleven). Lego Stranger Things aimed to recreate the main characters in Lego form, including Barbara "Barb" Holland, Eleven / Jane Hopper, Mike Wheeler, Lucas Sinclair, Dustin Henderson, Will Byers, Joyce Byers, Chief Jim Hopper and the Demogorgon.

Development
Lego senior model designer Justin Ramsden said he worked closely with Netflix to design The Upside Down set: "they gave us loads of behind the scenes images and plans." He said, "We also got the chance to create three new elements for the set as well, they are headgear for the Demogorgon, a hair piece for Dustin and also the hair for Will." He further explained, "With the Stranger Things set, we started off with a concept sketch. There was an elite team of LEGO designers that joined together to discuss what this model could be. From that meetings, one of the concept designers drew a quick sketch and that became the basis for what the model could look like. We followed the sketch and had a close dialogue with Netflix. There was some back and forth with them, and we did iterations that made the set more stable, more playable and with more functions."

Launch
In 2019, Lego Stranger Things theme was launched at The LEGO Store in Flatiron District, New York. Later, it also launched in the UK at Lego Store Leicester Square, London. As part of the marketing campaign, The Lego Group released The Upside Down (set number: 75810) based on a version of the Byers' home.
