CoMix Wave Films and director Makoto Shinkai have announced a new animation project that focuses on the formation and movement of several types of clouds. Sora no Kumo is planned for early 2015, and is said to explore various shots of clouds at different times of day, including clouds against the sunset.

Shinkai explains his desire to explore multiple types of clouds, including cirrus, nimbus, and “those really high ones that appear really fluffy.” Shinkai also confirmed that the film will feature unrealistically reflective objects and voice actor Irino Miyu.
