The Warcraft movie adaptation has already completed principal photography, but there's still a ton of visual effects work that needs to be done - in order to bring the movie's fantastical world and characters to life.
That means the film won't be ready for a theatrical release for some time (it's currently scheduled for the first quarter of 2016), but that didn't prevent director Duncan Jones from showing new material at the 2014 Comic-Con in San Diego. A Warcraft conceptual teaser premiered during the San Diego Comic-Con back in 2013. However, for this year's Legendary Pictures Panel, Jones brought something a little more substantial, to show the thousands-strong crowd in Hall H.
First, Jones talked a bit about the narrative for Warcraft, saying it'll be an origin story that addresses how war breaks out between orcs and humans on the world of Azeroth. He also mentioned that he's designed the film to be accessible to a wider audience - having personally rewritten the earlier script draft by Charles Leavitt (Blood Diamond) - thus, opening the property up to moviegoers unfamiliar with the brand, similar to the approach on past fantasy series such as Harry Potter, Lord of the Rings, etc. That explains the reasoning behind having the film adaptation draw inspiration from the earlier game installments in the Warcraft franchise.
The Warcraft teaser that followed was narrated by both a human and an Orc from the film (each seemed to be reading from their war diaries), indicating that the movie will very much examine what leads to the conflict between the two races from both of their perspectives (think Dawn of the Planet of the Apes). Most of the footage was focused on depicting the various environments and landscapes of Azeroth, there was also some material teasing actual battle sequences involving the two clans.
As for the CGI Orcs in the film - they're clearly far from being finished in the teaser footage, so it remains to be seen how good (read: photo-realistic) their physical design will ultimately be - once they've been fully-rendered, that is.
Warcraft opens in U.S. theaters on March 11th, 2016.
