The production vlog is here to stay. The latest online production video diary comes from the makers of 300, the adaptation of a graphic novel by Frank Miller (Sin City) and Lynn Varley about the Battle of Thermopylae. So far, there’s just one entry posted, and from the looks of it, it appears that the movie is being shot almost entirely on a blue-screen soundstage. That may not make it the most realistic depiction of ancient Greece, but it does resemble the artwork in the panels of Miller and Varley’s graphic novel. Check it out.
