Many types of film production insurance are used for specific types of production elements that you might be using. If you hire an aircraft as part of your production you will need to secure a specific type of aircraft insurance that is curtailed to film production specifically. The same is going to be true for acquiring and using railroads, specific types of boats, and even a special insurance for cars in certain cases. This will usually be the case with special types of vehicles, especially expensive and period ones actually used in front of the camera.
Animals will also require a special type of insurance, and this is going to be a more complicated process even beyond this. When deciding the specific type of animal related film production insurance that you need, you should talk to the animal trainers that you are using as well as the locations you are using them in.
