David, Gillian and Chris talked to the LA Times about the future after Season 11 of The X-Files. Entire article can be found -- here.
As for this being the end in The X-Files, Anderson is resolved — “This is it for me,” she said — but Duchovny isn’t ready for that conversation, pointing out that he himself left the show at one point during its original run.
“Gillian said it's been it before ... I don't know. We can make pronouncements or we could say, ‘Well, Fox might not want more.’ Who knows? I have no idea, so I'd rather not even dwell on the hypotheticals of it. I'd rather just enjoy these 10.”
Time will tell, but for now, Anderson says, “It has been an extraordinary gift and I'm incredibly grateful for the existence of Scully in my life and for the gift that Chris gave me in casting me, and my friendship with David, and it's been a wonderful run, but I've got other things to do.”
For his part, Carter said he needed to focus on finishing up this season but could envision being struck by an idea of where to go next. “That happens all the time,” he said. “Every time I pick up a newspaper there's something that sparks.”
