Spike TV recently aired a preview of the short film The Babysitter, one of seven similar films that will make up Halo Legends. This particular film was animated by Studio 4°C, who also worked on The Animatrix and Batman: Gotham Knight.
Halo Legends is due for a Fall 2009 “limited release” (likely on Xbox Live) and a spring 2010 “full release”.
Some of Japan’s most prestigious studios, including Toei, Production I.G. and Studio 4°C have announced their participation in a Halo anime project calledHalo Legends. This anthology series will feature stories from various parts of Halo’s backstory, including “the history of the Spartan warrior class” and “the entire 100,000 year history of the Halo universe”. This project seems extremely similar to previous multi-studio collaberations like The Animatrix and Batman: Gotham Knight, both of which Studio 4°C participated in.
