Das Kabinett des Dr. Caligari

There's one little moment that stood out for me when I watched this movie years ago on the USA network:

Glynis Johns spends most of the movie in some sort of conflict with Dan O'Herlihy playing Dr. Caligari...it's the sort of psych-out contest seen in every episode of The Prisoner and other war-of-wills dramas. Up to this point Ms. Johns is rather prim and after a while this can become irritating to viewers who are used to seeing female protagonists stand up for themselves more vigorously. After a frustrating argument with Dr. C, she runs upstairs, throws herself on the bed and (instead of sobbing or sulking, as her uptight character has behaved so far) lets out a huge WAAAAAA-HAAAAAAH! My girlfriend and I both collapsed with laughter ...but after that moment found ourselves much more in sympathy with her, and that is precisely the effect intended by Robert Bloch.

Overall the movie was worth the time it took to watch, but didn't stand out as a favorite for either of us. But when we encountered something frustrating after that, we'd look at each other and shout, "Waaaa-Hahhh!"
