Django Unchained – Man looses wife, man tries to find wife, man finds wife
Finding Nemo – Mon looses son, man tries to find son, man finds son
Those two have very similar stories but the details are very different.
Django is filmed with real people, violent and with in a very distinct time persiod.
Finding Nemo is a childrens film, animated and the time period can be deciphered but its not as important to the story as it in Django.
