Corrected entry: When Mary is walking back home from school in one of the first scenes, you can see quite clearly that she is wearing a black/brown skirt, but when she is in the desert, she is wearing a white/grey skirt throught thoes desert scenes.
Walkabout (1971)
1 corrected entry
Directed by: Nicolas Roeg
Starring: Jenny Agutter, David Gulpilil, John Meillon, Luc Roeg
Plot hole: It doesn't make sense that Mary is English with a heavy English accent, while both her brother and father are obviously 'Aussies'. Even if she was adopted to an Australian family, she wouldn't claim to be English, she would be a naturalised Australian.
Correction: Australian schools have a winter and summer uniform for girls. In spring and autumn, they are worn more or less alternately.
