When Aliens Attack is the theme for this edition of Film Music Friday. Movie aliens always seem to want to enslave us, destroy us or eat us (sometimes all three). We'll hear themes from some classic alien invasion movies, including The Thing from Another World, The Day the Earth Stood Still, War of the Worlds, Kronos, Alien and Mars Attacks.

Starting in the early 1970's, the London-based National Philharmonic Orchestra produced a long string of albums devoted to classic movie music.  On this week's Film Music Friday, we'll hear some of those memorable records, with music from The Adventures of Robin Hood, Lost Horizon, Airport, The Fountainhead, The Jungle Book and more.

This week on Film Music Friday, it's music from the films of Alfred Hitchock.  Hitchcock was a true auteur, a filmmaker whose influence and artistic control was so profound that he is truly the author of his films.  And that’s nowhere more evident than in the  music. We'll hear excerpts from classic Hitchcock films such as Rear Window, Rebecca, Strangers On a Train, Vertigo and Psycho, among others.

The chase has been a staple of cinema since the days of the Keystone Kops. On this edition of Film Music Friday we'll hear excerpts from some of the great "chase" movies, including North by Northwest, White Heat, Catch Me If You Can, The Bourne Ultimatum and others.

Composer Ennio Morricone died on July 6 at the age of 91.  In this edition of Film Music Friday, we remember the Maestro with some of his best-known film scores, including music from The Good, the Bad and the Ugly, Once Upon a Time in the West, Cinema Paradiso, The Mission, The Untouchables and more.
