"Chris Carter, writer, producer, and director of The X-Files: I Want to Believe, was hospitalized on Tuesday due to "physical exhaustion and an acute sleeping disorder," a source close to Carter (pictured, right, with David Duchovny and Gillian Anderson) tells EW.com. The source says the hospitalization stems from Carter "working on multiple films back to back over a two year period" -- the recently released X-Files sequel and Fencewalker, a covert project he is rumored to have begun shooting earlier this year. He is expected to recover quickly."
