It's the end of an era at Fox: The X-Files will not be returning for a 10th season this fall, the network announced Wednesday. Creator Chris Carter decided to pull the plug on his long-running UFO saga — which has seen its ratings fall this season sans David Duchovny. "It's the ninth inning. We want to go out on top," he told Variety. "We wanted to go out as a strong show." It's Carter's hope that Duchovny will reprise his role as Fox Mulder opposite Gillian Anderson's Dana Scully for the show's two-part series finale.
