I guess this counts as animation: 20th Century Fox released their first "domestic" trailer for Walking with Dinosaurs (subtitled The 3D Movie) on iTunes Movie Trailers today, embedded above via YouTube.
The hybrid CGI/live-photography documentary based on the 1999 BBC miniseries opens in North America and a number of other markets on December 20. It's directed by BBC Earth creative director Neil Nightingale.
Done on a budget of $65 million (according to The Hollywood Reporter), the CGI looks very good—best ever for this type of thing. What I want to know is why Disney didn't pick up the distribution rights for its Disneynature label, especially since they had no theatrical release this year.
