Animal Crackers (trailer) is a 94-minute computer-animated children's movie. The brainchild of Scott Sava, it caught the early attention of furry fandom at least as far back as 2015. Concept animation showed a guy haphazardly munching on animal-shaped cookies that turned him into the animals. As time went on, Sava brought in financial backers, a co-director (Tony Bancroft, who'd worked on several Disney movies), and a co-writer (Dean Lorey). The finished product premiered at the Annecy Film Festival in 2017... and then vanished.
It turns out that Sava had made the mistake of not securing a distributor ahead of time. With very little bargaining power, it eventually got shown in China in 2018, and some other countries in 2019.
