^ I always have a locked set of mind that Joker = skinny & well dressed, even if he's crazy.

Personal opinion on this: Heath is abit bulky, and the make-up is certainly not like how the usual Joker @ noticed the obvious messy lipstick.

Must wait till a good trailer to know how he would really look like

(pic for reference)

Nah, Jack does not have a big face like Heath up there.
Maybe what's inside every Batman director's mind is that if skinny & smart-dressing = The Riddler

But anyway, I took a look at a different Heath's face angle:


Maybe he looks bulky on one side but not the other, so can say much like Jack anyway haha! (self-contradiction ftw)

But anyway, this is a fan-made poster of the new movie
