Amazing Special Effects That Were Actually Made For Cheap
Escape from New York
3D New York City
Escape from New York featured a computerized 3D model of New York that was frankly too expensive for the film's budget to actually be created. So the special effects department went a different route. They took the mini model of New York that they had already used in other scenes, and went to work on it with green tape and a blacklight. The resulting image looked like a genuine 3D model of the city rather than something created using stuff you could get from your local store.
