An early start in stop motion 8mm film making propelled Aaron Sims on a career trajectory through Hollywood. He assisted with the gooey practical effects for cult 80s movies such as "From Beyond," "Evil Dead 2," and "Gremlins 2." The sleazy, show-stealing worms for "Men in Black," were created by Aaron, and he applied his knowledge of prosthetics and puppetry to the CGI robots in Steven Spielberg's "A.I. Artificial Intelligence."

Now Aaron heads up Aaron Sims Creative, a concept art and VFX company which has designed creatures and locations for movies such as "Independence Day: Resurgence," "Logan," and "Wonder Woman." In this entertaining podcast, Aaron talks about creating the terrifying Demogorgon for Netflix series "Stranger Things," choosing between practical effects and CGI, and the importance of always moving forwards.
