Diane Keaton and Eugene Levy will voice Dory’s parents in Finding Dory, Collider is reporting. The plot will involve Dory on a quest to find her long-lost family, only for Marlin and Nemo to have to go and find her. Possible minor spoilers found within the article indicate that the ending of the movie has already been changed due to the documentary Blackfish, which takes a negative look at marine theme parks such as Sea World. Given that the movie is years away, that entire sequence may end up being left on the cutting room floor, but either way audiences can look forward to Finding Dory on November 25th, 2015.
