From Diablo Wiki
This cinematic was released at Blizzcon in October 2008. It introduces the Wizard character, and shows off some of the monsters and dungeons beneath the Tristram Cathedral, culminating in a showdown with the undead spirit Leoric, the Skeleton King. Gameplay footage is mixed into the production.
This is not a true pre-rendered cinematic from the Blizzard Cinematics Department. It, like the Monk intro cinematic was produced using the Diablo 3 game engine, machinima style.
