3. Rags the Dog in Sleeper
Being a Woody Allen film,
Sleeper naturally is about a neurotic lead character. This character is awakened in the future to fight an oppressive government. I don't want to get too much into the specifics of this film because I am not a major Woody Allen fan, but suffice it to say it is a funny movie with somewhat dated humor. However, Rags is an awesome robot dog and one you've surely forgotten about (or never even knew existed).
2. The Stepford Wives
I know, I know; everyone knows the Stepford Wives from either the original or the remake. They barely belong on this list. I'm including them for the same reason I included Dot Matrix - you probably remember them, but when's the last time you thought about them?
The Stepford Wives is one of those films that permeated the culture. In the 1970's, you knew what a Stepford Wife was even if you'd never seen the film. The robots are creepy but intriguingly sexy to the male mind. Unfortunately, they don't always obey the Three Laws. On the surface they are perfect adherents to the Laws, but there is a violent streak in the wives that allows them to kill a human.
