All hail Frank Bryce, the only Muggle to mock Voldemort towards his face. True, he did die, but the old man had balls of steel, befitting of a World War II veteran.
"Lord is it? Well, I don't think much of your manners, my Lord. Face me like a man, why don't you?!"
Cedric, Fleur, Krum, and Harry in the first task of the Triwizard Tournament.
In the second task, Harry stubbornly refuses to leave other prisoners; he comes in last but is awarded second place for his "moral fiber", as Fred and George put it, and more importantly wins respect from the other competitors.
Harry and Cedric deciding that it didn't really matter which one of them won the tournament, instead just doing it for the honor of Hogwarts. In hindsight, this may not have been such a good idea.
When Harry stepped forward to face Voldemort. He knew that he was about to die. But he would not die crawling and begging for mercy. Daniel Radcliffe's expression for that moment just sold it. Completely.
