Off to a terrible start, this rambles on for roughly half its length about pre-production problems in Oz. Ten writers, including Ogden Nash and Herman Mankiewicz, bounced on and off the MGM project. Finally, the film credits would read ""Screenplay by Noel Langley, Florence Ryerson and Edgar Woolf. Adaptation by Noel Langley."" But what they left out, what they included, and what they changed--which is all given so much space here--is incomprehensible to anyone who doesn't know the film by heart. Finally, one gets to the crucial issues, and things improve slightly. D'you know about the time Toto sprained his foot and his trainer had to be medicated for a nervous stomach. Or that it took six tries to get the shoes right. Or that Ray Bolger considered himself more intellectual than his co-stars, and that none of them were allowed to eat in the commissary. . . they looked too disgusting with their elaborate make-up half on and half off. Margaret Hamilton developed a green tinge from hers that took several weeks to wear off after the shooting stopped. And Judy Garland was polite. Cultists will love this. We were Oz-ed 'out half way down the road.
