The final spell that Harry Potter uses in the books + movies is "Expelliarmus". Though he does catch Voldemorts wand and use Voldemorts own spell against him, but Harry doesn't actually cast that one, Voldemort does.
As part of Voldemorts character, he was just made with no nose. As he grew and became more evil, his appearance had to become uglier, so they made him have no nose. To make the actor have no nose, they simply used make up and face putty to make the actor look as though he had no nose. The graphics of voldemorts "no noseness" gets better as the movies go on as better make up is being produced and so are special effects.
