Writer/Director Robin Hardy wrote "Cowboys for Christ" as the spiritiual continuation of "The Wicker Man." The book received scant publishing in the United States.
Undeterred, Hardy intended to recast Christopher Lee and Joan Collins as the patriarch and patriarch of a Scottish town. Lee injured his back and production was delayed. Eventually Hardy offered Lee a cameo role as "the Old Man," who may or may not be Lord Summerisle from the previous movie.
Despite his protests about how horrible Nicholas Cage's "Wicker Man" was, "The Wicker Tree" seems to have more in common with Cage's remake than it does the original version.
The one consistent thing about Robin Hardy's "Wicker" series is the beautiful music that is utilized as both a soundtrack and as a storytelling device.
There is talk about a third movie in Robin Hardy's "Wicker Man Trilogy" that is to involve the Nordic Religions and the end of the world as we know it.
