The War of the Worlds
My overriding memories are, funnily enough, not of the book, or the movies, but of Jeff Wayne's fabulous album. My father used to play it over and over in the car and those strident first chords used to scare me in a way that late-70s Dr Who never did. I still get a tingle when I hear that music and I'm cursing myself for missing the live tour this year. Next year... without fail!
