The X-Files: Mulder and Scully Aren't the Only Characters Returning for Fox's Revival

At least two familiar faces will join Mulder and Scully on Fox's upcoming X-Files revival.

On Tuesday night, series star David Duchovny appeared on the Late Show with David Letterman and revealed that the Cigarette Smoking Man (William B. Davis) and FBI Assistant Director Walter Skinner (Mitch Pileggi) will also be back for the six-episode season.

The Cigarette Smoking Man a.k.a. Cancer Man a.k.a. CSM was Mulder's chain-smoking nemesis. But now that smoking is such a big no-no on network TV (as NBC's Constantine learned the hard way), we have to wonder whether CSM will be losing his signature cigarette.
