I know that my question is very blurry, so here is some more detail:
I only know the rough plot: The story takes place in the future, where Planet Earth is completely destroyed. The survivors are looking for a giant space ship or space object that could provide the possibility to live on. I am not sure but I thought the name of the object was "Titan" or something like that. As far as I can remember, the movie should be drawn/animated, not computer generated, and should be like 20 years old or younger. I am not sure if it is an Animé. I am fan of postapocalyptic settings and would be very glad if anyone had any suggestions to help me find the movie I am looking for. Thanks in advance.
