How VFX Emmy nominees 'Westworld,' 'Vikings' and others transport TV audiences

There's a new paradigm in television laced with high-end visual effects for a more sophisticated viewing audience.

Visual effects designer Kevin Haug and VFX supervisors David Stump and Jeremy Ball focused on photographic realism to develop the look and feel of Starz's "American Gods" with director David Slade.
