John Doe (The X-Files)

"John Doe" is the seventh episode of the ninth season of the American science fiction television series The X-Files. The episode first aired in the United States on January 13, 2002, on the Fox network. It was written by executive producer Vince Gilligan, and directed by co-executive producer Michelle MacLaren. The episode is a "monster-of-the-week" episode, a stand-alone plot which is unconnected to the mythology, or overarching fictional history, of The X-Files. "John Doe" earned a Nielsen rating of 5.0 and was viewed by 5.28 million households. The episode received largely positive reviews from television critics.

The show centers on FBI special agents who work on cases linked to the paranormal, called X-Files; this season focuses on the investigations of John Doggett (Robert Patrick), Monica Reyes (Annabeth Gish), and Dana Scully (Gillian Anderson). In this episode, Doggett wakes up in Mexico with no memory of who he is or how he got there. Meanwhile, Reyes and Scully struggle to locate him. The two later discover that Doggett's memory has been taken by a "memory vampire" that works for a drug cartel.

"John Doe", which was written after Gilligan had been thinking of a story involving a "memory vampire" for months, was MacLaren's directorial debut. Noted director Kim Manners helped guide her through the process. Director of photography Bill Roe used specific lighting for the episode; indoor scenes are dark and hard to make out whereas outside scenes are bright and over-saturated with light. The Mexican hotel apartment was created from Fox Mulder's (David Duchovny) old apartment set.
