Rita Tushingham is Gorgeous in This
I had seen the film on TV very late at night years ago, and only remember her and her white boots and miniskirt--most of the other details were lost to me. Now seeing it on Youtube it reminds me stylistically of Lester's other directed films, "A Hard Days Night" and "How I Won the War" with very short episodes or sketches tossed together without any rhyme or reason except to make some really good jokes, but then quickly resume the plot. Actually some of the jokes are pretty unexpected and laugh out loud types.
Tushingham's mini was still there on my second viewing, but her boots are brown in color, and never change throughout the production, so somebody somewhere is quite responsible for the "white boots" error.
The humor is very British--you have to be familiar with the stuffiness of the upper classes there to appreciate what they do with it on the ground. I love the backgrounds out at their chosen location: anybody see that river of mud that engulfs dozens of now-useless cars? Man, that's fantastic. It reminds me of Dylan's great line, "(I have) a thousand telephones that don't ring, can you tell me where to get rid of these things?"
Seeing it on Youtube is best; you can move ahead when things get boggy onscreen, which happens every few minutes.
