Duncan Jones directed 2016's Warcraft movie that is replete with special effects (aren't all movies these days?). Over the past day or two, Jones has been sharing a bunch of clips on Twitter. They show off behind-the-scenes action, including a troll invasion of Stormwind that was later cut from the film to shorten its duration. You can also see a bit of Karazhan and Elwynn Forest.
Check out all of the clips on Duncan Jones' Twitter.
