Harry Potter V Main Casting is Finished!

Imelda Staunton (queen of the period film) has been cast as Dolores Umbridge, the most evil and heartless Harry Potter character I have ever read (and she isn't even a death-eater!). Staunton will have fun playing the disciplinarian.

Tonks, the shape-shifting witch, will be played by Natalia Tena.

The other coveted spot of Luna Lovegood went to and Irish schoolgirl named Evanna Lynch. She beat more than 15,000 hopefuls. Luna is a nerd and a conspiracy nut. It's going to be fun to see her on the screen.
