The award-winning actor remains best-known for his role as FBI Agent Fox Mulder in the sci-fi/horror drama, alongside Gillian Anderson as Dana Scully.
“It’s fantastic to be part of it,” he said.
“At first it’s a little frightening and feels like a strait-jacket. But as time goes on, you just learn to be grateful.”
Duchovny used Adele’s album 21 to explain his X-Files achievement.
“I was reading about Adele in the New York Times, and they were asking a producer about the pressure for her to come up with another 21, and he said, ‘you find one unicorn in the forest, that’s an amazing thing. To find two in the forest, that just doesn’t happen’.
“I guess at some point, I came to grips with the fact that The X-Files is my unicorn and I’m not going to have another success like that – nor do I really want to. It’s enough to have one phenomenon, I don’t need two.”
The X-Files has so far spawned two feature films, a spin-off series and numerous items of merchandise. Originally broadcast from 1993 to 2002, the paranormal-themed US drama series returns for a limited run in January 2016.
In the opening episode of the revival, Mulder and Scully take on a case involving alien abduction.
