Warcraft director Duncan Jones stands up for the use of CGI in film

Warcraft director Duncan Jones has taken to Twitter to defend the decision to use CGI in modern films.

"I hear this 'CGI in film sucks,' mantra again & again," Duncan wrote in a series of tweets stemming from a discussion over whether Hollywood overuses computer-generated imagery. Duncan defends the use of CGI as a "tool" that has the potential to have both good and bad results, depending on how it's used.

"It can be done well & it can be done sh**. The best CGI has you forgetting its CGI, and accepting the visual as whatever it is supposed to be. Like props. No one has an issue with 'props' in film, do they?"

Responding to one Twitter user who argued that films without CGI garner better performances from the actors, Jones maintained it's the job of the director to coax out the performance. With reference to the famous "chest-burst" scene in Ridley Scott's Alien, Jones wrote: "why would you think that a director couldn't use the same technique to get the performance & not still enhance the alien?"

Filming of the live-action movie based on Blizzard Entertainment's World of Warcraft franchise was completed early last year; however, the movie will take an additional 20 months of post-production. Actors Paula Patton, Dominic Cooper, and Ben Foster will star in the film which is scheduled for a March 11, 2016 cinema release.
