‘X-Files’ Revival Taps Mitch Pileggi for Return

“Walter Skinner will once again be getting all grumpy and bitchy ,” actor says

It’s official: FBI assistant director Walter Skinner is back on the case with “The X-Files.”

Mitch Pileggi, who played Skinner on the original series, has been booked to reprise the role on Fox’s upcoming revival of the series.

“Very happy to announce that Walter Skinner will once again be getting all grumpy and bitchy with his two wayward kids,” Pileggi tweeted. “Very happy.”

Of all the secrets surrounding the famously secretive series, Pileggi’s return wasn’t one of the bigger ones. “X-Files” star David Duchovny recently told David Letterman that Pileggi is expected to come back for the revival, as is William B. Davis, known to “Files”-ophiles as the Cigarette-Smoking Man.

Pileggi received congratulations from colleagues, including “Hannibal” creator Bryan Fuller, who tweeted, “Wouldn’t be the same without you, Mitch!”

The conspiracy-obsessed series, which ran for nine seasons and aired its finale in 2002, is being brought back by Fox as a limited series for a six-episode run.

In addition to his work on “The X-Files,” Pileggi is known for his acting on the FX biker drama “Sons of Anarchy” and TNT’s recent “Dallas” revival, among others.
