SAN DIEGO (AP) — Chris Carter was cool to the proposition of a third "X-Files" film, but series stars David Duchovny and Gillian Anderson were decidedly more amenable.

Whether the truth is out there about any third film in the big-screen franchise remains as murky as the alien black oil that featured prominently in the popular Fox television series, which ran from 1993 to 2002 and spawned a pair of feature films.

In a panel Thursday at Comic-Con International, the actors, series creator Carter and the show's producers and writers reminisced about the series' groundbreaking stories as well the complicated relationship shared by FBI agents Fox Mulder and Dana Scully.
