And then there were none (1945).

Fascinating notes here on the copyright status, how it feel into the public domain and the reaction afterwards. As noted here from Wikipedia:

Though it was distributed by a major studio, 20th Century Fox, the copyright was allowed to lapse and the film is now in the public domain. Several different editions of varying quality have been released to home video formats.

The name of the film sometimes varies with who listed it. In 1960, Radio Times altered the title to Ten Little Niggers for an airing of Clair's film on BBC television on 9 July, the original title of the novel as published in the UK.
Sensitivity to the original title of the novel was remarked by Sadie Stein in 2016, commenting on a BBC miniseries with the title And Then There Were None, which she said "has been an enormous hit in the UK." In general, "Christie’s work is not known for its racial sensitivity, and by modern standards her oeuvre is rife with casual Orientalism." The original title was based on a rhyme from minstrel shows and children's games, "a rhyme so macabre and distressing one doesn’t hear it now outside of the Agatha Christie context." Stein quotes Alison Light as to the power of the original name of the island in the novel, Nigger Island, "to conjure up a thrilling ‘otherness’, a place where revelations about the ‘dark side’ of the English would be appropriate."Speaking of the "widely known" 1945 movie, Stein added that "we’re merely faced with fantastic amounts of violence, and a rhyme so macabre and distressing one doesn’t hear it now outside of the Agatha Christie context." She felt that the original title of the novel in the UK, seen now, "that original title, it jars, viscerally."

Another reality of Public Domain works is that they often are released multiple times by various media outlets in the same year. Between 2000 and 2018 there were at least fifteen releases of And Then There Were None on DVD and one on Blu-ray from different distributors as can be seen in this listing from All Movie linked below.
