Worst adaptation?
Ugh, I have to say the 1944 version of The Cantreville ghost is awful. It's nothing like the book it's based on. Why is it the version starring Neve Campbelle can be true to the book but not this? It's terrible. Sir Simon's own father has him sealed in a room to starve to death for not fighting in a duel that wasn't even his to fight and now someone has to figth a duel in his honour or some such nonsense. It's far from the actual book where a teenage girl pleads with the angel of death for Sir Simon because he had caused his wife's death. An the 1944 version is listed as a comedy! It's much darker than Oscar Wilde's original story and it's awful.
The version with Patrick Stewart is much better and true to the book even though it's set in the nineties.
