The film contains 117 visual effects shots, all of which are designed to be "invisible". When the Visual Effects Supervisor, Kwesi Collisson, solicited bids from VFX houses, he received an initial estimated VFX budget of over $1 million, followed by a $400,000 "low budget" estimate. Mr. Collisson decided to execute all of the effects himself, spending four months using Adobe After Effects and Shake software to complete the necessary shots.
