This week on “Picture Perfect,” you’ll be spellbound (I hope), as I present an hour of musical selections from movies about wizards and sorcerers.

Gandalf and Saruman duke it out in Peter Jackson’s frenetic, yet somehow ponderous adaptations of J.R.R. Tolkien’s “The Lord of the Rings,” films so bloated and poorly paced that anyone who had not read the books probably wondered what all the fuss was about. Its abundant defects didn’t keep the screen trilogy from making over a billion dollars and garnering 30 Academy Award nominations. Three of those were bestowed upon composer Howard Shore. We’ll be sampling from his music to “The Fellowship of the Ring” (2001).

Made for a fraction of the budget, much less self-serious, and arguably way more fun is “The Sword and the Sorcerer” (1982), which holds no pretense to be anything beyond what it is: a schlocky B-movie sword and sandal swashbuckler. However, the composer, David Whitaker, aspired for something greater. Against tremendous time pressures, he turned in a marvelous score, which sounds like Erich Wolfgang Korngold on a shoestring. If this film had been made by George Lucas, Whitaker would be world famous.

After creating one of his greatest scores for Stanley Kubrick’s “Spartacus,” Alex North had his music for Kubrick’s “2001: A Space Odyssey” rejected – and not in a nice way. (North didn’t find out about it until the lights went down at the film’s premiere.) Fortunately, the composer was able to salvage the best material for “Dragonslayer” (1981). The plot, about a bumbling sorcerer’s apprentice who faces a seemingly impossible challenge, is serviceable at best, but the dragon may yet be the most amazing committed to film. Also, the score is terrific.

Finally, John Williams kicks off another billion dollar franchise with “Harry Potter and the Sorcerer’s Stone” (2001), which in England was released (as was the book) as “Harry Potter and the Philosopher’s Stone.” Who ever heard of a sorcerer’s stone? I guess the publishers were afraid Americans would be put off by any association with philosophy.

I hope you’ll join me for wizards and sorcerers this week, on “Picture Perfect,” this evening at 6 ET, with a repeat tomorrow morning at 6; or that you’ll listen to it later as a webcast at http://www.wwfm.org.
