Long before production began on Thor: The Dark World, director Alan Taylor enlisted the help of VFX company The Third Floor to help with their pre-visualization process, which allows the filmmaker to map out sequences before shooting them. Today, we have a featurette that shows us some of those early scenes in pre-viz, and how they compare to the finished product in this Marvel Phase Two sequel. This video also includes footage from the set and director Alan Taylor himself describing this process.
