Throughout July, Wang Yang had been busily spending his days in Vancouver, and by the beginning of August, the pre-production work for the "District 9" crew, such as sets, props, and costumes, had all come to a satisfactory end; what remained was waiting for the production to be completed. The special effects team had already created a 3D full-body image of the Cimex species and Christopher Foersten and his son, which made him very pleased, although the alien spacecraft and mech suits still required more time.
Once the work in Vancouver was mostly settled, he returned to Los Angeles. Aside from preparing the photography equipment needed for the start of filming, finding stuntmen specialized in explosions and car stunts, finalizing some minor role actors, and discussing promotional plans with the distribution department for "District 9," he also had to follow the "Sweetheart" crew for a few days of filming and attend the premiere of "High School Musical 3."
