I strongly doubt that there were two films of the life of the burglar Charles Peace made in 1905 and this identification of the film as being by Mottershaw is incorrect. It was long thought to be the case until William Haggar's daughter Lily-May saw the film in a Welsh cinema as part of a compilation of early films puit together by Alberto Cavalcanti and recognised the film and herself as the actress playing Peace's avccomplice (several of her siblings also perform in the play including her brother Walter who plays Peace while her mother Sarah also appears as Mrs. Peace). Since then the film has been correctly identified as being by William Haggar.
It is obviously possible that Mottershaw also made a film especially since Peace was from Sheffield but, in this case, it is much more probable that it is an earlier film than Haggar's and a date, sometimed ventured, of 1903 seems more likely. But it is still the case that there is no very good evicence for the exitence of any such film and it rests purely on a critical tradition )everyone repeatin, often word for wword, what the last critic has witten, and that critical tradition is itself probably based simply on the initial misidentification of the Haggar film.
