Every film production company should consider having this coverage on their insurance plan. Once the footage is captured and stored on film or digital cards you can expose (no pun intended) yourself to new perils: For instance what if the post production team goes to download the files and they are corrupt somehow? Or what if the director accidentally takes the cards through airport security and for some strange reason the footage gets wiped from the cards. In order for these types of losses to be considered, the production company would need faulty stock coverage endorsed on their insurance coverage.
