But if you will remember, the ORIGINAL THE WIZARD OF OZ (1939) bombed at the box office. It took till 1956 for MGM to recover from that one.
When the movie RETURN TO OZ was made by Disney, was released, Joel Siegel went on TV and actually shed tears that they had tried to upstage the “greatest movie ever made!”
It certainly bombed with me, when I first saw it on a black-and-white TV in 1959. I was fascinated with the story until the ending, which I thought was a cop-out (the whole thing was merely a dream) and still do, today.
If you want to see a movie version of "The Wizard of Oz," watch the 1925 movie starring Larry Seman and Oliver Hardy (before he teamed up with Stan Laurel). It's light years better than the 1939 talkie.
