I Am Legend
One of the most gut-wrenching scenes in ‘ I Am Legend ’ was this scene with the dog. When Robert (Smith) is attacked by the mutant dog, his own dog protects him but unfortunately becomes infected too. But did you ever wonder how they filmed that scene? All it requires is a man in an awkward tight green suit holding a prosthetic dog. Oh, and some amazing acting skills by Will Smith.

The original plan for part of the film was to have the infected people played by real people wearing make-up and prosthetics, but the tests results made them look more like “angry mimes,” as the crew said. The choice was then made to use CGI to depict the creatures instead.
