"Rarely has the arrival of a film at the Packard Campus occasioned as much anticipation as the day in April 2015 when the sole surviving nitrate print of the first cinematic adaptation of Frankenstein (Edison Manufacturing Company, 1910) was accessioned into our collection. It’s not because the film is all that revelatory—it’s most decidedly not—or because it’s especially rare, as a quick search on YouTube will attest. Rather, this is an instance in which the story of how this particular reel came to be in our collection is more interesting than the film itself."
