Science Friday LIVE came to Caltech on Wednesday night, for a fun-filled evening exploring the intersection between Hollywood and science. Fortunately, you can listen to the audio if you missed the event. Program highlights included Making Hollywood Digital Doubles: USC scientist Paul Debevec and Avatar actor Stephen Lang talked about how convincing “digital actors” are made, and what Debevec’s success could mean for the future of acting. Also: Science in the Writers’ Room: Scott Z. Burns (Contagion, An Inconvenient Truth), Zoanne Clack (Grey’s Anatomy) and Eric Kaplan (The Big Bang Theory) on how they balance scientific accuracy and storytelling. Also again: From the Lab to the Silver Screen: The Birth of CGI. Animator Tom Sito explained how scientists and engineers kickstarted Hollywood’s digital animation revolution.
