Comic-Con 2013: David Duchovny confirmed for 'X-Files' 20th anniversaryAdd to Favorites | The X-Files
Although Gillian Anderson's attendance was confirmed by the Official Gillian Anderson website on Wednesday (June 26), this is the first full confirmation that Duchovny would in fact be joining her. The Unofficial SDCC blog first reported the news on Wednesday, July 3. Michael Schneider, the moderator of the panel, confirmed the news to the blog.
If last year's "Firefly" 10th anniversary is anything to go by, fans of "The X-Files" should plan to line up for Ballroom 20 early. SDCC hasn't announced when it will open lines on Wednesday (attendees can't even pick up passes before then), but it's likely that the line for "The X-Files" will begin shortly after that.
In addition to the "X Files" panel, Anderson at least will also take part in the "X-Files" Comic Book panel on Friday (July 19) and will sign autographs at the Lightspeed Fine Art Booth (dates and times TBA). There is no word yet on whether Duchovny will follow suit.
