Very similiar in production to Jack The Ripper 1988
As the credits and the music at the beginning of this film started rolling, I thought to myself this looks and sounds familiar, and I was right! It's very similar in production to Jack The Ripper that Michael Caine also starred in two years before in 1988 ...

It has the same writer and director, and many of the locations have been used in this that were used in Jack The Ripper as well. Mind you, the younger male extras in Jack The Ripper didn't have late 1980's hair styles as most of them do in Jekyll & Hyde, maybe they didn't have enough wigs! lol
