To properly understand this bizarre X-Files tale of the crew’s naked adversary, you need to know a bit more about the episode in question. “Shadows” was a season 1 episode that was a bit different, focusing on a vengeful ghost rather than aliens, monsters, or shady government conspiracies. This was at the request of 20th Century Fox, which went out of its way to ask the series’ writers to start telling ghost stories.
The ghost in this episode goes out of its way to protect a woman named Lauren from various threats, including two assassins sent to kill her. To bring this scary plot to life, the show’s crew had to shoot a nighttime scene where the attackers were coming for the woman in question. On paper, this sounds like a pretty straightforward X-Files scene, but the crew ended up encountering one man’s (literally) naked wrath due to how late they were shooting.
