The splendid new three-disc extras-packed collector’s edition of The Wizard of Oz is a tribute to two mighty forces that revived its genius for two new generations: television and "Wicked."

Television made the 1939 classic an instant hit with baby boomers when it began its annual broadcast in 1956, so it’s fitting that it’s back on the small screen in DVD. Now, in a new century, the fabulous musical "Wicked," told from the Wicked Witch’s point of view, sends fans back hungry for this exquisitely restored original. The second and third discs should sate the curiosity of the biggest Oz-maniac with interviews, outtakes, deleted scenes and, yes, even composer Harold Arlen’s home movies.

Best Extra: All those replicas of original programs in the two enclosed Collector’s Treasury folders, overflowing with background information and promotional art.

Bottom Line: Follow the yellow brick road. It takes you where you want to go.

DVD Grade: A
