Blomkamp works with RATEL VFX in Vancouver, a small studio specializing in TVC VFX. He is represented by RSA Films in Los Angeles, and Spy Films in Toronto. Blomkamp employs a documentary-style, hand-held, cinéma vérité technique, blending seamlessly with naturalistic and photo-realistic computer-generated imagery effects.
When plans for the film eventually fell through, Jackson and Blomkamp instead started production on District 9. Many elements from the cancelled Halo film were re-used or adapted for District 9, including the basic Warthog and Pod infector designs.
