Alternative title
An alternative title is a media sales device most prominently used in film distribution. Books and films are commonly released under a different title when they are screened or sold in a different country. This can vary from small change to the title, such as the addition of The, to wholesale changes. Film titles are also often changed when they are released on DVD or VHS.
