Behind the Scenes of Stranger Things

Stranger Things caused actual bike sales to surge after Season 1 aired. That iconic image

of kids pedaling through Hawkins made everyone nostalgic. But here's what most fans don't

know. Eleven's name isn't creative writing, it's her literal experiment number,

011, tattooed right on her arm at Hawkins Lab. The Upside Down

that looks so digital is actually built with real sets, covered in actual slime and practical

effects. Vecna's terrifying appearance required seven full hours in the makeup chair

every single filming day. That creepy clock ticking in Season 4 was designed using

classic horror movie sound techniques. And the show almost had a completely different name.
