Blacklight Castle- Mystery Film: Silent Film: Lost Film, Found Magazines

Is the silent film The Mystery of Room 643 a lost fim? It appeared in Picture Stories Magazine as a fictionalized, or rather an adapted, photoplay during 1914-1915. The film starred Francis X. Bushman who portrayed Richard Neal, private investigator. The following year Bushman starred in The Return of Richard Neal.

The Riddle of the Green Umbrella was featured in 1915 as "from the Kalem detective story" and featured Alice Joyce as a "girl detective" solving the murder of a professor. The film is not listed as being lost or missing, but is also absent from lists of films that are not lost. Pictures Stories Magazine advertised itself as being the "Illustrated Films Monthly" on its cover.

Another film that seems questionable as to whether there may be existant copies of it or not is Stars, Their Courses Change (three reels, 1915) which was featured with a full page magazine advertisement.

The Anna Q. Nilsson film The Thundering Dawn was featured on magazine covers during 1923 and is listed among films that are lost or were left unrestored. Next appears her film Ponjola, a film that seems to be left unlisted in filmographies as being either existing or missing. It is not missing from libraries. A copy of the photoplay rewritten into novel form by Cyntheia Stockley was published by Gosset and Dunlap Photoplay Edition the year of the film's release.

Films made by The Stoll Film Corporation at first seemed like there were more likely to be lost than those made by other companies. During 1923 there were The Tidal Wave and Bars of Iron. Any film featured as an adapted screenplay in Picture Stories Magazine during 1914-1915 could now be a lost film. His Last Chance reads 'adapted from an IMP drama by Rosa Beaulaire'.
