Many students of Daws Butler (the original voice of Yogi Bear) sent Dan Aykroyd tapes of Butler explaining how to do Yogi's voice. Aykroyd refused to listen to any of the tapes, preferring to do his own take on the classic character.
Yogi, the cartoon character, has an iconic pose often used in comic books, advertising, etc. He is leaning, one arm extended, legs crossed at the ankles. Ranger Smith replicates this pose in the background of one scene.
The film was primarily shot in New Zealand, as it was winter in the northern hemisphere and to wait for summer would delay the shooting schedule longer by six months longer than if in southern hemisphere.
