But as he prepares to film a new, six-part mini-series, featuring a slightly wrinklier David Duchovny and Gillian Anderson, he must know that he has to bridge a gap that divides not just chapters, but whole generations and cultures. While excitement fades among recovered X-philes the question follows: can they pull it off?
The show was huge, running for more than 200 episodes from 1993 to 2002. It made stars of Anderson, who played FBI agent Dana Scully, the sceptical foil to Duchovny's tortured conspiracist, Fox Mulder. Believing that his sister had been abducted by aliens, Mulder used his assignment to the FBI's unsolved cases - the X-Files - to find her, and uncover a conspiracy implicating the government and aliens.
At first, Scully hit him over the head with science, before stuff got too weird to ignore, they fell in love and had a weird baby.
The show was a triumph because it defied genre norms. I hated sci-fi and was too much of a wimp to like horror, but I bloody loved The X-Files. It had the production values we now take for granted in posh TV, and tapped into, yet also challenged, popular, paranoid interest in the paranormal; you didn't have to be a conspiracy nut to enjoy it. It was also, arguably, the first web-aware show, inspiring fans to commune online in the dial-up age.
"But above all, people just like a bloody good story," says Jonathan Maberry, a writer and X-phile. He has edited a new anthology of original X-Files stories, endorsed by Carter and Fox Television. His book, X-Files: Trust No One, is due to be published in May. He has no inside track on what shape the new episodes will take but is confident that a cult hit turned popular classic can be revived to achieve similar appeal.
"I think Mulder and Scully will vet new agents, who will probably be a lot more cynical about global politics," he says. "There'll be storylines about the theft of information by companies and governments. Whistleblowers could feature, as well as wars fought for reasons other than actual defence."
He wonders if Carter may dare to look towards a post-9/11 Middle East for inspiration. "I can foresee stories where someone in Isis might be driven by a desert demon," he says. "It could use sci-fi and horror folklore to explain some of the extremes of modern global politics."
Maberry, a best-selling horror author, also sees potential in the rise of the drone to make alien stories feel less like relics of the Nineties. "I would be surprised if the show didn't use a drone story as a way of exploring how UFOs were able to hide among us by looking like the toys we now have."
Times, technologies and viewing habits have changed during Carter's commercial break, but the truth, whatever it now looks like, is still out there - probably. Above all, as Fox execs know well, they have a captive audience of Nineties nostalgists. A word of warning from this one: don't mess with the theme song.
