CGI effects are par for the course in superhero films these days. It’s likely that you sit through the credits at Marvel films to check out post-credit sequences, so you’ve probably seen the very long lists of people who work in the effects departments. Computer-generated effects are a specialized skill – sometimes directors know a lot about the process, and sometimes they rely more on the specialists to create sequences and tell them what is possible for a scene.
IGN got a chance to speak to the VFX department for Avengers: Endgame, including Dan DeLeeuw, and Captain Marvel’s Shannon Justison, Janelle Croshaw Ralla and Nick Crew. They told us all about working with directors, and what they prefer in terms of director knowledge about their craft.
