The X-Files focused on the exploits of FBI Agents Fox Mulder, Dana Scully, John Doggett and Monica Reyes and their investigations into the paranormal. From genetic mutants and killer insects to a global conspiracy concerning the colonization of Earth by an alien species, this mind-boggling, humorous and occasionally frightening series created by Chris Carter has been one of the world's most popular sci-fi/drama shows since its humble beginnings in 1993.
