So I saw this film years ago and all I can remember is that it's about a boy(roughly between the age of 9 and 14) who is unwanted by his parents and is abandoned in a forest by his father and all I remember from that is that the boy ends up in an old abandoned car underwater where he meets this statue of a female and I think a spirit leaves the statue? I'm not sure how the boy ended up in the water but maybe the car was drove into the water? And I'm pretty sure he is down there for a few years but I'm not certain of that.

A.I.: Artificial Intelligence (2001)
Starring Haley Joel Osment
IMDb synopsis:
In the not-so-far future the polar ice caps have melted and the resulting rise of the ocean waters has drowned all the coastal cities of the world. Withdrawn to the interior of the continents, the human race keeps advancing, reaching the point of creating realistic robots (called mechas) to serve them. One of the mecha-producing companies builds David, an artificial kid which is the first to have real feelings, especially a never-ending love for his "mother", Monica. Monica is the woman who adopted him as a substitute for her real son, who remains in cryo-stasis, stricken by an incurable disease. David is living happily with Monica and her husband, but when their real son returns home after a cure is discovered, his life changes dramatically.
