Corrected entry: In the world of Issac Asimov robots, the three laws are immutable. At the beginning Andrew makes a lavish presentation of the three laws. At the end of the film, Galatea breaks the first law (not to harm) in order to conform to the second law (obey orders). The three laws are hierarchical in that the first law takes precedence over the second. In Asimov stories, the contradiction between the laws most often causes paralysis of the robot in question.
Corrected entry: 'Little Miss' (Grace) is shown to be about 5-7 years old at the beginning of the movie, and her sister Amanda is about 5 years older than that. When 'Little Miss' is shown as a young adult 15 years later, she is apparently somewhere around 20-25 years old. However, her 'older' sister Amanda is shown to still be a teenager 'making out' with her boyfriend on his motorcycle. The sister is about ten years younger than she should be according to the storyline.
Corrected entry: Isaac Asimov's famous "Three Laws of Robotics" are stringently enforced within this movie. However, when Andrew is told to jump out the window by Amanda early in the film, this would have been in direct conflict with the law that states that a robot "must protect itself and cannot do self-harm unless to protect a human from harm." Andrew jumping out the window cannot reasonably be explained as protecting any human from harm.
Corrected entry: Towards the end of the scene of the party that celebrates the opening of a building that Portia restored, if you look closely at the bottom of the screen, you can see one of the couples dancing with the guy leading with his right hand, instead of his left, like everyone else. (01:33:15)
Corrected entry: When the clocks all chime at 4 o'clock, the cuckoo on one of the clocks "chirps" 7 times, even though it is only 4.
Corrected entry: I think we can be pretty sure that Andrew is pretty heavy, but in the scene where "little miss" finds the horse that he made, the bed hardly sinks at all. (00:18:25)
Corrected entry: The chronology for this film is entirely wrong. At the very beginning of the movie, we are told that it is somewhere in the not too distant future and we see that the family gets the robot. It cannot be too far in to the future, since the family car has a 1999 type California license plate. The little girl, who is about 7, grows up and has a granddaughter and they are both alive at the same time. However, later we find that, while the granddaughter is still alive, the robot has lived 200 years. Either these two women must have lived extraordinarily long lives for this to happen, or the robot was created many many years before the little girl at the beginning of the movie was born. But we are told the year of the robots manufacture which is somewhere around 2012. This means that the robot had to have been created and sat on the shelf 60 or so years minimum and then sent to the family with the 1999 license plate.
