To create one of the year's most critically acclaimed animated movies, production designer Yashar Kassai and his team of artists had to “unlearn everything we learned in art school, and frankly, draw shittier. Like a kid who’s 14 or 15.”

Kassai worked as production designer on Teenage Mutant Ninja Turtles: Mutant Mayhem, the latest in a new wave of animated movies with distinct art styles and broader audiences — and it couldn’t come at a better time.

Aside from Zack Snyder and a handful of studio executives, Jay Oliva may know more about DC’s original plans for a cinematic universe than almost anyone. As a storyboard artist, he worked on major DCEU movies including Man of Steel, Batman v Superman, and Wonder Woman. He also directed some of DC’s best animated films, like The Dark Knight Returns and Flashpoint Paradox. But it’s the movies that never saw the light of day that get him the most excited.

Oliva is a wealth of knowledge on pretty much everything DC (up until he parted ways with the company in 2017), and that includes Ben Affleck’s scuttled Batman movie, which remains shrouded in mystery even six years after the actor walked away from the project.
