Which we all already knew when Duchovny spilled the beans a while back.  ComingSoon reports that filming is starting December 10th, with the filming name of "Done One."  (Well, it's no "Rory's First Kiss," but okay.)  Chris Carter and Frank Spotnitz wrote the script.

Last month, X-Files series star David Duchovny said, "[T]he script is written and as far as I know we're all trying to shoot in December at some point. We would all love it if we could keep it a secret and just give everybody a fresh experience of not knowing what the movie's about."

In other movie script news, "Spider-Man 4" has a new writer attached.  James Vanderbilt ("Zodiac") is penning the script for a planned 2009 release.
