Perhaps the most fortuitous outcome of the Dean films at Universal is that they introduced Browning to future collaborator Lon Chaney, the actor who would star in Browning's most outstanding films of the silent era. Chaney had already earned the sobriquet "The Man of a Thousand Faces" as early as 1919 for his work at Universal. Universal's vice-president Irving Thalberg paired Browning with Chaney for the first time in The Wicked Darling (1919), a melodrama in which Chaney played the thief "Stoop" Conners who forces a poor girl (Dean) from the slums into a life of crime and prostitution. In 1921, Browning and Thalberg enlisted Chaney in another Dean vehicle, Outside the Law, in which he plays the dual roles of the sinister "Black Mike" Sylva and the benevolent Ah Wing. Both of these Universal production exhibit Browning's "natural affinity for the melodramatic and grotesque." In a special effect that drew critical attention, Chaney appears to murder his own dual character counterpart through trick photography and "with Thalberg supporting their imaginative freedom, Chaney's ability and unique presence fanned the flames of Browning's passion for the extraordinary." Biographer Stuart Rosenthal remarks upon the foundations of the Browning-Chaney professional synergy: When Thalberg resigned as vice-president at Universal to serve as production manager with the newly amalgamated Metro-Goldwyn-Mayer in 1925, Browning and Chaney accompanied him. The Browning-Chaney collaborations at M-G-M: 1925–1929 After moving to M-G-M in 1925 under the auspices of production manager Irving Thalberg, Browning and Chaney made eight critically and commercially successful feature films, representing the zenith of both their silent film careers. Browning wrote or co-wrote the stories for six of the eight productions. Screenwriter Waldemar Young, credited on nine of the M-G-M pictures, worked effectively with Browning. At M-G-M, Browning would reach his artistic maturity as a filmmaker. The first of these M-G-M productions established Browning as a talented filmmaker in Hollywood, and deepened Chaney's professional and personal influence on the director: The Unholy Three. The Unholy Three (1925) In a circus tale by author Tod Robbins—a setting familiar to Browning—a trio of criminal ex-carnies and a pickpocket form a jewelry theft ring. Their activities lead to a murder and an attempt to frame an innocent bookkeeper. Two of the criminal quartet reveal their humanity and are redeemed; two perish through violent justice. The Unholy Three is an outstanding example of Browning's delight in the "bizarre" (though, here, not
