What character’s prolonged stare was the most intense?

It can be Jack Nicholson’s blubbering teary-eyed stare in About Schmidt’s over the letter from his sponsor kid, his life finally having some kind of bit of meaning…

… or it can be Jack Nicholson’s deranged stare in The Shining as the energy of the Overlook Hotel works it’s way through him and awakens something…

… or it can be someone other than Jack Nicholson. As unlikely as that sounds.
