One of the few times I willingly do category fraud. He didn't make my list, but I can see arguments for both lead and supporting so I just go with Oscar and put him Lead. Chilling and iconic, a big reason I love that film so much.
So happy for my boy, Jimmy. One of my favorite actors and this is my favorite performance of his (though Mr. Smith really needs a re-watch). I suppose this also means he'll be missing for Vertigo which is a shame.
