The Psychotronic Film Society’s award-winning series of overlooked or marginalized feature films offers a special treat for fans of both Sherlock Holmes and silent movies: the rarest film featuring that master detective known to exist, 1916’s “Sherlock Holmes.” Lost for decades, this silent B&W motion picture is the first time the character of Holmes ever appeared on film, and it is considered to be one of the most influential films of its type.

In fact, many of the trademarks of later film and TV incarnations of Arthur Conan Doyle’s brilliant investigator can be traced directly to this film and the charismatic performance of William Gillette — who not only wrote the play this film was based on (and its screenplay), he also plays Holmes, as he had for more than 1,500 stage performances throughout the world before this film was made. Unseen for well over half a century, a single surviving print of this film was unexpectedly discovered overseas a couple of years ago, and has now been painstakingly restored. The PFS will present it fully uncut, on the 101st anniversary of its initial theatrical release.
