from Internet:
A classic of horror fiction from Robbins, about a trio of circus freaks who escape captivity in the circus, open a curiosity shop, and use it as a base from which to launch a devastating crime wave. Basis for two films, the first a silent classic in 1925 directed by Tod Browning and starring Lon Chaney (as Professor Echo the ventriloquist), Victor McLaglen (as Hercules the strongman), and Harry Earles (as Tweedledee the dwarf); the second version was directed by Jack Conway in 1930 as a talkie, with Chaney and Earles reprising their roles, and Ivan Linow as Hercules.
