Main infobox. The image is used for identification in the context of critical commentary of the work, product or service for which it serves as poster art. It makes a significant contribution to the user's understanding of the article, which could not practically be conveyed by words alone. The image is placed in the infobox at the top of the article discussing the work, to show the primary visual image associated with the work, and to help the user quickly identify the work, product or service and know they have found what they are looking for. Use for this purpose does not compete with the purposes of the original artwork, namely the creator providing graphic design services, and in turn the marketing of the promoted item.

As film poster art, the image is not replaceable by free content; any other image that shows the same artwork or poster would also be copyrighted, and any version that is not true to the original would be inadequate for identification or commentary. Not replaceable by any free-license representation of the film, as none exists. The original theatrical poster serves is the most preferable visual representation of the film from a historical or aesthetic standpoint.

As of the time of upload, a version of the poster at Commons claims the image is public domain due to a lack of copyright notice. However, with sufficiently high resolution (check the source link above), it is clear that there is a copyright notice: "Copyright 1976 Columbia Pictures Industries, Inc. All Rights Reserved." The poster could not pass into the public domain by failure to renew the copyright, either, because it was published after 1963.
