It turns out one of the most outspoken advocates for getting a third X-Files movie off the ground is Agent Mulder himself, David Duchovny. The actor was on The Tonight Show this week to promote the sixth season of Showtime's Californication, but he also told Jay Leno that he is still holding out hope for a third film in the series' big-screen saga, following 1998's successful Fight the Future and the not-quite-so-successful sequel I Want to Believe, which followed ten years later.
"We always want to," he said, referring to himself, co-star Gillian Anderson and series creator Chris Carter. “We're always on board.” He went on from there to asks the show's fans to start writing letters to Fox Studios to “get 'em going” on greenlighting another film. "I'll play Fox Mulder forever," he said, adding that they could still “wheel him out” to play him if he's too old to stand up.
His fellow guest J.B. Smoove (Monsters University) enthusiastically lobbied for a part as Mulder's sidekick, saying that he's seen a UFO himself. “I had a witness too,” he said. “That's the best thing. You got somebody next to you to say you ain't drunk!"
