I had not seen this but the company: LionsGate films shot the movie The House of D with Good Morning Vietnam star: Robbin Williams and Celebrity David Duchovny. As Director of this film David created at the LionsGate directors page a: Weblog, VideoCast en Podcast site
WOW .. that’s to attract your fans and audience .. a good tool to promote ‘the film’

Ron Moore is doing the same (including podcasts) for the new series of BattleStar Galactica but as they are shooting season 2 now the blog is not updated for 1 month almost.
