I don't remember much about the film but I do recall that it was about a female robot or cyborg that was married to a human man and some how was able to give birth to a child. I think her husband and child (it was a girl) were unaware of the fact that she was a robot, in fact I think her husband was a politician or something whose political party was against robot rights.
...Sorry if that information is terrible. I watched about half the movie years ago and I just recently remembered it. If you could help I would be SO grateful! I just spent an hour googling "movie about a robot that had a baby" :P
