The Flash has no shortage of incredible visual effects to blow your mind during the series. With a much bigger special effects budget than most TV shows, he found himself up against some incredible sights and experiences, all brought to life through the use of computer animation.
The clip goes through the incredibly painstaking process of making a fully-computer generated character like Gorilla Grodd feel real. They went so far as to make vital organs for the rendered Gorilla, which is more than most would do. This gave Grodd more of a realistic feel to him.
Check out the video below. The Flash returns on October 6th, 2015 on The CW.
