Not the short story; instead, a 2005 exercise in retro film making. This is a silent black-and-white gem of a movie. A faithful adaptation, it’s wonderfully lit, has a fine soundtrack, and was actually pretty gripping for all 47 minutes.
The retro special effects are surprisingly effective; the “non-Euclidian geometry” so beloved of Lovecraft makes some novel appearances toward the end. Thoroughly recommended.
