The 34th Annual Saturn Awards took place last night with numerous filmmakers and celebrities in attendance and answering questions on the red carpet about their upcoming projects with Collider.
Most notable is that director Zack Snyder ("300") was there and claims he's fighting hard to keep as much as he can from the comic in the final film. From the sounds of it the studio has been concerned with the edgier elements and the runtime which he's still pretty dead-set on keeping at 150-180 minutes theatrically.
Snyder confirmed that did show off a 20-30 minute sizzle reel to the studio with a couple of completed visual effects, but mostly green screen footage.
The Comic-Con footage will be several minutes long and he seems pretty ready for the fact that the footage will end up on Youtube soon after its shown at the Con. Some props may be on display at Comic Con but its not been confirmed.
Finallly he said that the production should easily make the March release date, whilst the DVD - with the Black Freighter add-on - could hit 210 minutes or possibly higher.
