Mystery of the Wax Museum (1933), directed by Michael Curtiz.
A cross between Jack-the-Ripper and Phantom of the Opera, overshadowed by its more famous remake, House of Wax (1953) with Vincent Price.
Something of a muddle of chills and laughs, with a big action scene at the end. The melting wax figures during the first scene are pretty ghastly. It's a pleasant enough 1h17m if you like the genre, and the visual design is intriguing.
Pre-Code, but that just means one of the madman's helpers is a junkie rather than an alcoholic. Fay Wray may show more leg art than would have been done a little later.
One of the last feature films made in two-color Technicolor. It was a compromise technique, but in retrospect we miss it sometimes, that antique look of early film. You can get plugins for paint software to simulate the look. Retro-adventure stories sometimes try to recapture it, as in Sky Captain and the World of Tomorrow (2004):
