Jekyll & Hyde is a 1990 tv movie starring Michael Caine in the dual title role. Cheryl Ladd is his sister-in-law and illicit love interest, a character I don't remember from the book. Lionel Jeffries plays Jekyll's father. I don't like this one, even though I like Michael Caine in almost everything. This version has entirely too much unrelated romance and romantic scandal thrown in to suit me. I haven't finished watching it, and I may not.
The New York Times has a review.
