This is one of a handful of Metro-Goldwyn-Mayer productions of the 1950-1951 period whose original copyrights were never renewed and are now apparently in Public Domain; for this reason this title is now offered, often in very inferior copies, at bargain prices, by numerous VHS and DVD distributors who do not normally handle copyrighted or Metro-Goldwyn-Mayer material.
