Take a Look Back at All the Harry Potter Movies Before Friday's Grand Finale (VIDEO)

Only one day remains until the U.S. release of the final installation of Harry Potter films, "Harry Potter and the Deathly Hallows: Part 2," and even the most diehard fans are finding themselves in need of a little refresher.

The series has evolved from J.K. Rowling's adult-friendly fairy tale for children to (now six books and films later) what promises to be an explosive and very grown up grand finale. Lucky for all of us, Warner Brothers has just released a trailer that wraps them all up into one massive synopsis.

Watch Daniel Radcliffe grow from the impish little funny-glasses-wearing tyke of ye olden days into an intelligent and multi-talented actor and Broadway performer with some very adult problems. Watch Emma Watson blossom from a precocious, pretty little girl into the beautiful, elegant young lady currently gracing the cover of Vogue.

As the actors blossom, so do their characters and their powers, forcing them to take on a growing list of increasingly evil characters, from Draco Malfoy to the powerful and conflicted good/evil force of Severus Snape.

Speaking of which, how about that horrible demonic bastard Lord Voldermort? Man did he ever get hit with the ugly stick. When is Harry going to finally put that evil-lookin' Son of a Slytherin' out of his misery for good anyway?

Wait, you've read all the book? You can tell me? No don't - I'm waiting until tomorrow.
