Out of the four versions of Wuthering Heights available on DVD {1939, 1971 and 1992 being the others}, this is the closest to the book. It's far from being a perfect adaptation, the definitive version is still to come. Of course the 1939 version is artistically far superior to any of the others, but it's the least faithful adaptation. Both this version and the 1971 version stopped virtually half way through the story. The 1993 one did attempt to tell the whole story, but was somewhat stuffy and lacking in the intense emotion required. This TV movie, shown in two parts, is far more successful in telling the whole story, and certainly does not lack for emotion.
There are a few changes {maybe one day we will be able to see Heathcliff and Cathy first meet the Lintons as children rather than adults} and the first part of the story is rushed. There is the odd unnecessary touch, such as seeing Heathcliff semi-rape his wife. Generally,though,it's pretty faithful, does most of the great scenes in the book well and even adds a few details from the book that were not in the other mentioned versions at at all, such as Heathcliff tying up Isabelle's dog, or Heathcliff throwing a knife at her. Orla Brady is as close to the Cathy from the book as one can get, and while Robert Cavanagh is visually not an ideal Heathcliff, he really shows the evil of the character like few others.
Despite all this, this modestly produced version still manages to have a great deal of the required emotion, and despite Heathcliff's nastiness the filmmakers still manage to make one almost feel his pain and torment. The ending is beautifully done, aided by some very John Barry-like music.
It's not the perfect adaptation, but it will certainly do. However, a message for the next person to film Wuthering Heights- make it a lot LONGER!
