When these images are assembled and played back they produce a movie effect much like a real movie camera except all images are artificially created by computer.  It is possible to add a computer-created environment around the building to enhance reality and to better convey its relationship to the surrounding area; this can all be done before the project is built giving designers and stakeholders a realistic view of the completed project.

A mockbuster may be similar enough in title, packaging, etc. in hopes that consumers confuse it with the actual film it mimics, but their producers maintain that they are simply offering additional products for consumers who want to watch additional films in the same subgenres.
