In 1920, filmgoers were treated to no fewer than two different film versions of Robert Louis Stevenson's -Dr. Jekyll and Mr. Hyde. Let us mercifully bypass the cheapjack
Sheldon Lewis version, which updates the story and allows for a happy ending, and concentrate on the
John Barrymore version. Barrymore plays the humanitarian Dr. Henry Jekyll, who becomes obsessed with the notion of separating the Good and Evil impulses within every man. To this end, he develops a potion which unleashes his own darker side--the demonic Mr. Hyde. This was the adaptation which established the cliche of having both a "good" and "bad" leading lady, to parallel the doppelganger aspects of the Jekyll/Hyde personality.
Martha Mansfield is the good girl, while Nita Naldi, wearing costumes that were daring indeed in 1920, is the bad one (and, frankly, the more interesting one). To add even more intrigue to the Stevenson original, the adaptors borrowed the character of Lord Henry from Oscar Wilde's
The Picture of Dorian Gray in order to provide Jekyll with an evil mentor/blackmailer. The film's highlight is the transformation sequence, which Barrymore accomplishes without makeup. Sadly,
Dr. Jekyll and Mr. Hyde proved to be one of the last starring films for leading lady Martha Mansfield: she died horribly during filming of The Warrens of Virginia (1924) when her costume touched a discarded match and burst into flame. ~ Hal Erickson, All Movie Guide
