Check the copyright number when you decide that you would like to purchase rights to a film in order to make sure that the seller really owns rights to the film.
Decide whether or not you would like all rights or some rights.
Determine which rights will remain with the seller. Filmmakers sometimes wish to retain the rights to create sequels to their movies and use their characters in other films.
Have the seller agree to reimburse the purchaser for any litigation that occurs as a result of the film, such as if the film plagiarized from another source.
Purchase errors and omissions insurance in case a litigation occurs despite the efforts of the filmmakers to avoid it.
Decide whether or not you want the original author’s name to be in the advertising used for the film. Then ask the author’s permission to use his name and get the permission in writing.
Figure out if you would like to purchase the movie rights outright or as an option. Those who purchase options do not fully own the film, but have the right to use the film over a set period of time. This period can be renewed. Once the movie is finally used, the purchaser retains rights to it.
