Spielberg needs to go back to Jurassic Park, I have a feeling this will under perform, and it's so screaming Zemeckis. Plus I never really understand this genre of films, cross breeds of "realistic" animation with "CGI" aniamtion. Just either make a animated film or make a live-action film.
This is the second Spielberg film coming out later this year, and who's really going to watch film centered around a horse (War Horse)???
