Now commences a bit of build up, so I am afraid I may not have much to say here in the comments aside from, "Wait for it . . . !"
But as long as we've got one of those "silhouette cast along a (European brick) wall" shots, I may as well go ahead and gush briefly about the movie The Third Man. Have you seen it? It's brilliant. The first time I watched it, I was super bored, then I was super shocked, and then I was super into it. The second time I watched it I lol'd all the way through so now I'm under the impression that it's a hilarious almost-parody of a noir film. Only I'm not too good a judge of old movies so I could be completely off the mark.
The Third Man does a lot with shadow play-- and uses those shadows to set-up and subvert audience expectations. One particular scene has the massive shadow of a mob seemingly descend upon our protagonist, only to reveal that the mob's leader is a tiny child with a balloon. So cute! It's also set in Vienna, which is a lovely city to spend some narrative time in, and has a super intense threatening scene inside . . . a ferris wheel. Which is a real ferris wheel that still exists! And I've been up inside it! And yeah it's kinda scary in there. (Thanks for hosting me, Pia~)
