 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.
