In a Q&A promoting the upcoming "X-Files" sequel series, David Duchovny revealed which episodes of the series' return were his favorite, and discussed how working on the series -- alongside Gillian Anderson -- has changed since the show's end 14 years ago.

Duchovny told TVLine that the episodes written by Darin Morgan are his favorite in the sequel series -- citing the Morgan written/directed episode, "Mulder and Scully Meet the Were-Monster" (which airs February 1) as a prime example. "For me in terms of being an actor, Darin [Morgan]’s scripts — which were funny and whimsical yet very smart and rigorous — were always challenging and fun."

Speaking on the series' importance to his career, Duchovny said: "I always had an appreciation for it. It was a career-making show. Aside from my gratitude for whatever business it brought my way, it also afforded me a chance to go to work every day. If I ever did not have an appreciation for the show it was probably [during the final seasons] when I think we were just tired, and antsy to go out and do other things. I’m sure there were times when I was dying to get off the show, but it wasn’t because of the show. It was because it was a grind."

As for returning to the series alongside Gillian Anderson, Duchovny said their working relationship is healthier than it was near the end of the original series: "We’ve been good for quite a while work-wise. Whatever difficulties we may have had over the years [stemmed from] what I said earlier about wanting to get off the show… the fatigue and a hot-house feeling of being in the same room with the same people for nine years. We’re good now. We have a shorthand and I really enjoy working with her a lot. That was probably the easiest part of transitioning back into the show was our work together."

And could there possibly another season of "X-Files" after next year's event series? Duchovny doesn't "see why not," but notes, "...we don’t want to just make more episodes because we can. I’m not interested in that. And I don’t think [creator] Chris [Carter] is interested in that. If Chris is re-inspired to start thinking about where to take the show and the characters next I’m sure we’d all listen."

"The X-Files" returns to the airwaves Sunday, January 24 on FOX.
