London After Midnight (1927) is a silent mystery film with horror overtones. It is a lost film, quite possibly the most famous and eagerly-sought of all lost films.
Lon Chaney's makeup for the film is noteworthy, for the sharpened teeth and the hypnotic eye effect he achieved with special wire fittings which he wore like monocles. Based on surviving accounts, he purposefully gave the "vampire" character an absurd quality, because it was the film's Scotland Yard detective character (also played by Chaney) in a disguise. Surviving stills show this was the only time Chaney used his famous makeup case as an on-screen prop.
The last known print of the film was stored by MGM in Vault #7. In 1965, an electrical fire broke out in the vault that destroyed countless films from the silent era, including this last known print. However, rumors persist that one copy of the film may exist in a private collection in Canada and that the owner has declined to bring the print forward for preservation. On July 24th 2008, a story circulated of an eye witness who claims to have seen a nitrate print of the film in the late 1980s in a Hollywood archive, but the veracity of that story remains unconfirmed.
Finally, In 2002, Turner Classic Movies commissioned famed restoration producer Rick Schmidlin (Greed, Touch of Evil) to produce a 45 min. reconstruction of the film, using still photographs. This was well received by horror fans and Schmidlin received the Rondo Award for his efforts.
