The film was announced in March 1945. It was to be the first in a series starring The Spider Woman, like the ones Universal had for Dracula and Frankenstein. It was the second time Universal had spun off a horror series from their Sherlock Holmes movies, the first being The Creeper from
The Pearl of Death. The film was originally called
The Spider Woman Strikes Again and was based on an original story by Eric Taylor.
Ford Beebe was the original director attached. Much more production information can be found on the Tom Weaver-David Schecter audio commentary on Kino Lorber's 2021 Blu-ray release of the movie. In September Universal announced the film would be directed by
Arthur Lubin. Lubin said he "hated" the movie and did not want to do it but the studio threatened to put him on suspension otherwise. The lead roles went to Sondegaard, Brenda Joyce, Kirby Grant and Rondo Hatton. Lubin said "it was a stupid story" and that "I don't think" producer Howard Wlesh "liked it any better than I liked it" but that he enjoyed working with Sondegaard. ==Reception==
