The director of the upcoming “Warcraft,” Duncan Jones, said in a recent interview that the orcs in the movie look like they have the “genetic background” of the character Hulk. He also explained the filming challenges of the visual effects-packed movie.

The movie will be released in 2016 and is said to be nearing the completion of more than 1,000 visual effects shots. Speaking to Wired, Jones ("Source Code") revealed that only 50 such shots remained to be finished. The director noted that it was an “ambitious” project, but felt that the production team has created “something pretty special.”

The movie is based on the 1994 game by Blizzard, in which humans first encounter orcs in the fantasy world of Azeroth. The filmmakers used various methods to create the special effects, including motion capture technology, large in-camera sets and green screens.

Visual effects supervisor Bill Westenhofer is a two-time Oscar winner, while Industrial Light & Magic, the company responsible for some of the graphics in the movie, is represented by Jeff White and Jason Smith. White previously worked on the design of Hulk for Marvel’s “Avengers” movie, and the director of “Warcraft” felt that the orcs in the movie could be compared to the Hulk in terms of design.

White is said to be an “avid” player of the games on which the movie is based. Jones said finding a designer who was also a fan of the franchise was a “match made in heaven.” Blizzard is also said to have contributed concepts for characters in the movie.

Explaining some of the challenges "Warcraft" actors faced, Jones said cast member Clancy Brown had to sit on “something that looked a bit like a rocking horse” and pretend that it was a “giant beastly wolf.” The actor had to deliver an emotional scene as the character Blackhand while sitting on the “rocking horse.”
