"The overall atmosphere is a pitch-perfect evocation of period London, complete with dark, foggy alleyways, street merchants bawling out their slogans, men in top hats and women in flouncy dresses. Then, of course, there's Jekyll's laboratory full of Mysterious Equipment, Mrs. Hyde's signature blood-red outfits, bawdy beer halls, stained-glass windows casting splashes of color – lots and lots of nice sets and costumes and cool stuff. Not to be ignored, either, is the amazing similarity between Martine Beswick's and Ralph Bates' facial features, apparently a complete coincidence discovered only after the film had been cast. She really does look quite a lot like a beautiful female version of him, which adds a good deal of authenticity to the transformation sequences, accomplished solely through skillful trick photography." - Deneb T.
