Whoa! This is awesome. Get a look this stunning teaser for an animation project in the works called Cosmo Princess, created by an animation filmmaker in France named Quentin Rigaux (also known as Quentin Rgx on YouTube). This teaser debuted last year but we’re only catching up with it now – thanks to a tip from Cartoon Brew recently. It’s now being turned into a full-on 90 minute feature film by one of the producers of Flow, and he’s shopping it around & presenting it at markets to build up interest & get financing to develop it. Cosmo Princess is handmade 2D animation project with a style that is reminiscent of grainy, old school epic sci-fi animation from the 70s & 80s. Here’s the basic story intro: “Sometime, somewhere in the endless cosmos, a lost astronaut and cosmic princess collide. His hope: to return home. Hers: to escape her destiny of becoming a star. Fascinated by his tales of ‘Earth,’ she helps him find his way back, hoping to find refuge herself.” It looks amazing and I’m glad someone is letting Quentin turn this into an actual movie. I cannot wait to see more footage! Reminds me of animation like they used to make, but don’t make much anymore.

Intro via YouTube: “This is a small teaser I did for a story I’m aiming to bring to life someday — a fantastic space odyssey about fate and freedom, purpose and identity. A tale of stars and memories, and the fragile blue planet that ties it all together. Huge thanks to everyone who helped and supported me in making this little piece — and to you, for watching it.” Cosmo Princess is a unique sci-fi project created by animation filmmaker Quentin Rigaux, aka “Quentin Rgx” on YouTube, a graduate from Gobelins School in France who has worked for Wizz, Skydance, The Mill, Titmouse. He now works at Passion Pictures in Paris (follow him on IG @quentinrgx and on Patreon). It’s now being developed by Flow producer Ron Dyens (and his company Sacrebleu) as a full-length 2D animated feature film. “With Sacrebleu’s pedigree and the appeal of this gorgeous, lovable, and sincere story, I’m convinced that we will find trustworthy partners.” For more info, visit Cartoon Brew & stay tuned for updates from Quentin & Ron.
