It will come as no surprise to anyone that Stranger Things 5 required a lot of VFX work, but fans have been surprised to see just how much CGI was used in scenes that they thought looked highly realistic.
Industrial Light & Magic, the visual effects studio founded by George Lucas, has released a series of 'Behind the Magic' breakdowns showing some of their work on the hit Netflix series. As some fans have commented on the videos, the VFX sometimes feel like the Upside Down itself. “When we think it's CGI, it's not CGI. When we think it's practical FX, it's not practical FX,” one fan writes.
