There's definitely an old-school feel to it, but I think that's more dictated by the script... Good Night and Confessions both have differing styles so it's hard to figure out what they have in common.

You know what I think it is... I was going to say that they're movies wearing suits, but I think the style of the movie is the style of the wardrobe the lead character is wearing:  The fifties were proper and button down and ironed and that's sort of the feel of the movie, sharp, crisp, everyday elegance, and Confessions... in the "younger' days was a little more faded, it's the same suit you wear every day until you can afford a nicer suit with real material, then gets dressier when Chuck gets more money, and when he's at his lowest level, it's dirty.  And reality keeps unfolding around him... in Good Night reality is consitent, a freshly-done tie, and in Confessions it's loose and hanging and a little off-kilter and that's when you walk from one scene to another or do analog split-screens.
