The Wicker Tree was based on Hardy's own novel, Cowboys of Christ. But I kind of wished they made a direct sequel to the Wicker Man - as you said - some 40 years later kind of thing. As the Wicker Tree was a little disappointing.
I did read a few years ago (The Wicker Tree has been in production since 2007) that there is going to be a 3rd movie -making a trilogy sort of thing! would love to a return back to Summerisle
but whats actually planned is not quite the case
and to be fair The Wicker Tree is a 1000 times better than the Wicker Man remake
Yes I do agree with that statement, perhaps "Willow" can get her lips reduced in size & reprise her role? A re-visit, rather than a re-make of the story is always better, as a long time Supporter of Terry Nations 1970s Survivors BBC TV series, a 30 years on plot was my suggestion, but they did the re-make & made a huge mess of it, & that was that! The golden goose killed.
