I had read all three of these John Grisham books, and the films were almost as good. Tommy Lee Jones is a superb actor, and the clash between him and Susan Sarandon gave an interesting edge to the plot. One of the best performances was by the children's mother who tried hard to do the best for her children.
The Pelican Brief was also very good, and highlighted the hidden agendas played out in high places and political intrigue masking the truth.
The last film touched on sensitive issues of race and colour, and deep seated prejudice prevalent in parts of the USA. Of all three films, this was probably the best as it had more depth and twists, with a star cast.
