A couple movies worth exploring philosophically would be Finding Nemo and The Fugitive. Finding Nemo delves into how personal identity changes when people, or fish, are put into new or difficult situations. The Fugitive would be interesting to watch for the changing in ethics in the main character. Originally, he's a doctor but is accused of killing his wife. He escapes from prison to solve the mystery of who actually killed her and to clear his name. However, along the way he makes some questionable decisions. Are they worth it? Do the ends justify the means? It would make for an interesting look.
