The unusual montage in which Spencer Tracy is seen whipping two horses as the sultry faces of Ingrid Bergman and Lana Turner are transposed over them was often cut out of early television broadcasts for being too suggestive.

The long time love of Spencer Tracy, Katharine Hepburn, said in a 1986 article that Tracy had originally wanted the same actress to play both the female roles in Dr. Jekyll and Mr. Hyde.

Director Victor Fleming treated both Ingrid Bergman and Lana Turner roughly during the making of the film in order to get the reactions out of them that he wanted. Bergman loved him for it, but Turner hated working with Fleming.

Ingrid Bergman's character, the barmaid Ivy, does not exist in Robert Louis Stevenson's original story. Neither does Lana Turner's character, Beatrix.

Ingrid Bergman was originally cast in the role of Dr. Jekyll's fiancée Beatrix while Lana Turner was cast as Ivy. Bergman convinced director Victor Fleming to let them switch roles so that they could play against type and prove their range as actresses.

Actresses Patricia Morrison and Susan Hayward were reportedly tested for roles in the film.

Ingrid Bergman admits in her autobiography My Story that she fell in love with director Victor Fleming while making Dr. Jekyll and Mr. Hyde. Fleming, however, did not return her feelings.

Famous Quotes from DR. JEKYLL AND MR. HYDE

JEKYLL: Sometimes we have to gamble or haven't you the courage to face what might be the most daring...
DR. HEATH: Listen, Jekyll. I wouldn't talk these experiments around very openly if I were you. You're dealing with things that would be better not to mention for your own sake...there might be trouble.
JEKYLL: Trouble! Trouble!

JEKYLL (to Mrs. Marley): You know, I don't mind being scolded by the smartest hostess in London.

JEKYLL: Well, let me put it this way. Good and evil are so close as to be chained together in the soul. Now suppose we could break that chain. Separate those two selves. Free the good in man and let it go on to its higher destiny.

BISHOP MANNERS: Suppose we believe that man's soul has not yet reached its fulfillment. Is is wise? Is it right to tap over the problem until the creator himself has solved it in his own mysterious way?

SIR CHARLES EMERY (to Jekyll): You're a coming man in your profession. I'm very proud of you but these ridiculous experiments won't get you anywhere. You must give them up. Develop your practice. Cultivate the circle in which you and Beatrice should move.

JEKYLL (to Ivy): I'll tell you one thing. You wear your garter too tight. That stops the circulation...that's bad.

JEKYLL (to Beatrice): I make my own luck my dear. Yes, tonight, and tonight I followed the rainbow.

IVY: I ain't afraid of nobody.

MR. HYDE: When you went to see the good doctor, before you left you said...I almost thought, well what did you think? Maybe that you saw a little bit of ME, Hyde in him?

IVY: If I could only do it, I'd go down to the river.

JEKYLL: If you don't stop looking at me like that, I won't be responsible for what happens.
BEATRICE: Aren't public places awful sometimes?

IVY (displaying her scar): Pretty, ain't it? Did you ever see anything like that before?
JEKYLL: I'll get you some lotion.
IVY: Lotion? Twon't be lotion that'll do the trick sir. It's more than that. I need help. I can't stand it anymore. It's Hyde sir. It's a man I know.
