The human side of the Warcraft movie is best represented by two characters. The warrior Anduin Lothar (Travis Fimmel) and the young mage Khadgar (Ben Schnetzer). The two are brought together because of their connection to Medivh. Lothar and Medivh grew up together along with King Wrynn and Khadgar serves as Medivh's apprentice.
The two videos below give us an in-depth look at the two characters and how the interact. The somewhat sheltered and bookish Khadgar being drug into the battle by the charismatic and impetuous Lothar. This should be the fun interaction of the film in the same way Falcon and Winter Soldier got along in Captain America: Civil War.
Warcraft opens June 10th.
