"Surprisingly sophisticated to a point where it's easy to see why 1960 horror movie going audiences didn't flock to it, while many viewers of a more high brow nature wouldn't have been seen dead going to a Hammer film. Seen today though, its adult approach and persuasive amorality help make it hold up quite well... Just missing the mark as one of Hammer's greats, The Two Faces Of Dr Jekyll still has a lot to recommend it and is thoroughly enjoyable from beginning to end as long as you don't expect the usual blood and thunder. It reminds us very pointedly that it's what's on the inside that makes a man either good or bad, as well as being the last example in Hammer Horror of the greatness that was Jack Asher, a true genius of a cinematographer." - Dr Lenera, HorrorCultFilms
