Easily one of the highlights of this week’s San Diego Comic-Con takes place in Ballroom 20 on Thursday, July 18.

Con attendees who get in line early may be able to catch the 3:30PM “The X-Files” 20th Anniversary reunion!

While we already reported that Gillian Anderson, who played Agent Scully in the series, would be attending, it has just now been confirmed that David Duchovny, Agent Mulder, will be joining the celebration!!

It’s been two decades since FBI Special Agents Mulder and Scully first partnered to investigate unsolved paranormal cases. “The X-Files” made primetime safe for sci-fi, and spawned a generation of hugely successful writer/producers. Somewhere, the truth is still out there.

TV Guide Magazine Los Angeles bureau chief Michael Schneider leads a panel that is scheduled to include Gillian Anderson and David Duchovny, plus series creator Chris Carter and writers/producers David Amann, Vince Gilligan, Howard Gordon, Darin Morgan, Glen Morgan, John Shiban and Jim Wong.
