The Son of Dr. Jekyll is a 1951 American horror film directed by Seymour Friedman and starring Louis Hayward, Jody Lawrance and Alexander Knox.

[1] The film is a continuation of Robert Louis Stevenson's original classic 1886 novella Strange Case of Dr. Jekyll and Mr. Hyde.

Jack Pollexfen, the scriptwriter of this film, wrote and produced a sequel in the same vein, Daughter of Dr. Jekyll (1957), starring Gloria Talbott.

The film begins with a prologue set in 1860, where Mr. Hyde is chased down in the streets of London, after murdering his wife at their Soho flat.

John Utterson and Dr. Lanyon (original characters from Stevenson's novel) mourn their unfortunate friend Dr. Jekyll, until Inspector Stoddard brings the two to the Soho flat, where Jekyll/Hyde has left an orphan behind.
