Hyundai Capital
In addition to receiving financial support from the Hyundai Capital Corp. and Korean Technology Finance Corp., the film received financial and technical support from the Korean government (and the government of Suwon) by allowing the filmmakers access to military bases, hardware, and locations such as the Historic War Museum in Seoul, a location where filming has never been permitted before. The film utilized 124 miniatures and the designers spent 6 months designing Yonggary. Sculptures of the monsters were made in 6 months which were then scanned to digital screens for 3D work. Suits were produced for the monsters but were replaced with computer-generated imagery during post-production. The film was in production for 18 months and resulted in 45 minutes of computer graphics.
