I like the film, it really is something from another world now. But what really threw me was in the opening sequence.
Ginger Rogers is singing "We're in the Money" with the usual Busby Berkeley chorus, but half way through (about 1:40 in) she starts singing the song (what I thought was) backwards! A bit of digging around and it turns out she sings it in pig latin. Very strange but somehow enthralling, and very unexpected! It's great, even the odd in and out of focus the camera seems to do ...
