Roger Moore Hated It
I was recently reading Moore's autobiography, "My Word is My Bond", and somehow he was involved in the production of this Val Kilmer movie. I think that as a result of him playing The Saint in the 1960s, he somehow acquired a financial interest in subsequent Saint movies and TV shows.
In any event, he said in his book that he and the producers "really messed up" with this movie, and that it didn't capture the spirit of The Saint, in his opinion.
