I'am trying to find a movie, but I don't know the title. Can someone help me?

I don't know what year it was made. The plot is that bad guys are building a spaceship and are trying to send two of each animals. It is a sort of fantasy. It involves planes, the second main character's name is Polly. The main character has polly on the side of his plane. His base in in the air. That is all i know
