18 animated films will compete for Best animated feature this year. According to The Academy the number of nominees depends on the number of submissions:
All submissions sent to the Academy will be screened by the Animated Feature Film Award Screening Committee(s). After the screenings, the committee(s) will vote by secret ballot to nominate from 2 to 5 motion pictures for this award. In any year in which 8 to 12 animated features are released in Los Angeles County, either 2 or 3 motion pictures may be nominated. In any year in which 13 to 15 films are released, a maximum of 4 motion pictures may be nominated. In any year in which 16 or more animated features are released, a maximum of 5 motion pictures may be nominated.
With that being said there are 18 submissions this year, so there will be 5 Beast animated feature nominations. Here is a list of the submitted animated movies:
The Adventures of Tintin
Alvin and the Chipmunks: Chipwrecked
A Cat in Paris
Chico & Rita
Gnomeo & Juliet
Happy Feet Two
Hoodwinked Too! Hood vs. Evil
Kung Fu Panda 2
Mars Needs Moms
Puss in Boots
Winnie the Pooh
I think in the end it will come down to RIO or RANGO.
