“Since I began my animation journey,” Medrano shared, “my biggest dream was to be part of a feature film. Now to be creating an original story that I have been holding for years, and with Warner Bros. Pictures Animation, a studio whose characters and stories have been a huge part of my life, is truly a dream come true. I’m SO excited to share this fossil fantasy world with everyone!”
