Animation fans might recognize several of the sound effects added in post-production as familiar Hanna-Barbera library sounds, including explosions, car doors. The door opening sound heard off-camera during the sad scene immediately after Carol Lynley realizes the baby camel cannot be saved can also be heard in hundreds of cartoons.
Veteran Hanna-Barbera cartoon voice actor John Stephenson (Dr. Benton Quest, Mr. Slate, countless Cooby-Doo villains), is the uncredited voice of the helicopter pilot, first heard telling drivers to stay in their cars. Later, when the on-screen actor playing the pilot appears, his voice is still dubbed by Stephenson, perhaps for continuity reasons due to background noise in certain scenes.
