In grand "X-Files" manner, the as yet untitled film’s storyline is being kept under wraps, known only to top studio brass and the film’s principals. This much can be revealed: The supernatural thriller is a stand-alone story in the tradition of some of the show’s most acclaimed and beloved episodes, and takes the always-complicated relationship between Fox Mulder (Duchovny) and Dana Scully (Anderson) in unexpected directions. Mulder continues his unshakable quest for the truth, and Scully, the passionate, ferociously intelligent physician, remains inextricably tied to Mulder’s pursuits.
