WITH Fox’s “The X-Files” revival premiere less than a month away, the network is kicking into high gear with its marketing campaign.

    This week, Fox released “Re-Opened,” a 21-minute behind-the-scenes feature that offers what it declares is the “inside story” on the beloved franchise’s return.

    In the clip, creator Chris Carter as well as stars David Duchovny and Gillian Anderson take a look at the reasons behind the revival and spill secrets from the show’s new central story. The clip also offers a first look at the resurrected Lone Gunmen, Scully’s son as well as Joel McHale’s Tad O’Malley and Annet Mahendru’s Sveta.(SD-Agencies)
