I've never seen the 1988 'War of the Worlds' television series, but by practically all accounts, it was terrible. I wouldn't classify the original story it was based on as a work of horror - it's a work of science fiction, and I think that there have been more than enough television and film versions already so I wouldn't bother working out a script for yet another one. The most recent Hollywood version was laughably awful. It was so bad that a few critics walked out, and viewers were rolling in the aisles during the final scenes. There's a world of difference between adapting a book for the screen and making a film that's based on an existing work. The 1988 television series is not a true adaptation - the show merely uses the events of the book as the springboard to tell a new story that ties into those events. If I were being paid to come up with a few ideas, I'd likely cast Nick Frost as the unnamed narrator, Terence Stamp as Ogilvy, and Oliver Chris as the artilleryman.
