"Waxworks" is an early example in film history of a movie that's clearly in homage to another film--in this case, "The Cabinet of Dr. Caligari" (1920). The expressionistic stylization in the film is obviously influenced by "Caligari", and a few references to that film reinforces that, beginning with the title. The literal translation of "Das Wachsfigurenkabinett" is "The Wax Figures Cabinet"--the keyword being "cabinet". Additionally, the frame narrative is purposefully set at a carnival, although a more dimensional one than the stage setting in "Caligari".
The narrative structure is closer to Fritz Lang's "Destiny" (1921), with the framing of three odd stories. "Waxworks" has the clever device of a writer of the inner stories in the framing story. And, the three biggest stars of Weimar cinema (Emil Jannings, Conrad Veidt and Werner Krauss) play the historical villains and waxworks come alive in the inner stories. For the three stories, a different expressionistic technique dominates, each relating to and enhancing their respective themes. In the Harus al Raschid narrative featuring Jannings, it's the sets (Paul Leni's sphere) with oddly shaped architecture more akin to "Caligari' than Baghdad. Especially nice is the staircase set. Rather than the horrific, dreamlike abstraction of "Caligari", however, the sets are delightfully peculiar, as is Jannings and the silly story. Low-key lighting dominates the Ivan the Terrible episode featuring a darkly paranoid Veidt, and the multiple exposure kaleidoscope imagery places Krauss's stalking serial killer everywhere.
A clever film, and Leni and the other filmmakers seem to have had fun with it, which crosses over to viewers, but beyond that it's rather lackluster, not emotionally engaging as "Destiny", nor stunningly fresh as "Caligari".
