I feel like I'm in the minority here, but I don't think I agree on the "sinister" expressions. In my mind, when I think of Nicholson Joker, I think big huge, CRAZY looking smile. In terms of the FILM ITSELF, we see that "sinister" look very seldom. The shots of the "sinister" look all come from promotional shots, which I don't think reflects the Nicholson or the Joker that we actually end up seeing throughout the duration of the film.
don't get me wrong, he definitely flashes that sinister look a couple of times... but to me you can get that same sinister look along with the signature smile and teeth. I think the images from Partyman, with the sort of dropped jaw and... I dunno, something just looks off to me.
In the larger images I posted you get way more of the signature smile. The first one is a great one IMO.... big crazy eyes, wide smile... lots of expression. The final 3 images, which are smaller, are a good combination of "sinister" look but that still maintain the smile. And they don't have that odd looking (IMO) dropped jaw of those promo images.
